Available in PDF, EPUB and Kindle. Book excerpt: The replacement of polyols synthesized from petrochemical by polyols originating from natural products, notably from vegetable oils and animal fats, has been the subject of research projects for a number of decades. Very recently, however, the polymers industry has intensified its efforts to include the “green products”, such as biobased polyols, in applications already available in the market. Examples of such applications include polyurethane foams, elastomers and epoxides. This book describes the extraction of the natural constituents of several fruits and plants as well as their chemical conversion to polyols. In addition to the chemistry involved in the process, particular emphasis is attributed to their applications.

This book was released on 2019 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Replacing petro/fossil carbon by biobased renewable carbon derived from agricultural feedstocks offers the value proposition of (1) reduced carbon footprint, (2) supporting rural agrarian economy and improved food security, and (3) creation of "wealth" in the rural agriculture through manufacturing value-added industrial products. Our work reports on the synthesis of novel, scalable, and economically viable biobased polyols derived from soybean. Polyols find commercial use in the manufacture of polyurethane (PU) products, particularly flexible and rigid PU foams. Drop-in replacements of the currently used polyols with biobased polyols suffer from inferior performance properties with increasing biobased polyol content, high production cost, and incompatibility with petroleum-based polyols. The thesis also reports on the synthesis of novel polyols from meso-lactide and the production of value-added products therefrom. Meso-lactide is a co-product in the manufacture of polylactide (PLA). Polylactide (PLA) is the world's foremost completely biobased and fully compostable polymer with a production capacity of 140 kt/year by NatureWorks in Blair, NE and a 75 kt/year by Total Corbion PLA in Rayong, Thailand.The first section focuses on facile reaction chemistries to produce biobased polyols from a protein-carbohydrate residue derived from soybean meal or soymeal. The components of the soymeal were characterized to optimize processing options. The soymeal component was converted to polyols using transamidation chemistry, followed by a ring-opening reaction with carbonates. The process is cost effective with zero waste generated during the synthesis.In the second section, new biobased building blocks were synthesized from meso-lactide by reacting it with primary amines and alcohols. The ring-opening reaction of meso-lactide with an amino-alcohol produced diols containing amide and ester linkages in the backbone. These new biobased building blocks can be used to manufacture biobased polyesters and polyurethanes. Reacting meso-lactide with long-chain alcohols produces a diol containing ester and ether linkages with lower viscosity and hydroxyl value. This diol was further reacted with biobased dimer acid using polycondensation chemistry. A series of polyester-ether polyols with low viscosity and hydroxyl value (40-90 mg of KOH/g) were obtained which are suitable for applications in flexible PUF and coatings. The renewable carbon content of these polyols was 50-70% which can be increased to 100%.The third section focuses on evaluating the performance properties of PUF synthesized from biobased polyols. The biobased rigid PUF containing 20-50% of soymeal and lactide polyols were characterized for application as insulation materials in building and construction. The flexible PUF containing 10-50% of biobased polyol content were evaluated for automotive applications such as engine cover, car seat, and headrest.In the last section, reactive extrusion processing of lactide-dimer acid polyols with PLA was studied. The reactive blending of polyols with PLA increased the crystallinity of PLA by ~60-75% and decreased the glass transition temperature by ~18 °C. The elongation at break increased to 120%, and the impact strength was increased by 300%. The melt crystallization kinetics showed a reduction in the total crystallization time with increasing polyol content in PLA.To conclude the entire work, a series of cost-effective, scalable, diverse applications-oriented, and most importantly biobased, polyols were synthesized using inexpensive bioresources that have a potential for commercialization.

Available in PDF, EPUB and Kindle. Book excerpt: The vast majority of plastic products are made from petroleum-based synthetic polymers that do not degrade in a landfill or in a compost-like environment. Therefore, the disposal of these products poses a serious environmental problem. An environmentally-conscious alternative is to design/synthesize polymers that are biodegradable. Biodegradable polymers for industrial applications introduces the subject in part one by outlining the classification and development of biodegradable polymers with individual chapters on polyhydroxyalkanoates, polyesteramides and thermoplastic starch biodegradable polymers and others. The second part explores the materials available for the production of biodegradable polymers. Polymers derived from sugars, natural fibres, renewable forest resources, poly(lactic acid) and protein-nanoparticle composites will be looked at in detail in this section. Part three looks at the properties and mechanisms of degradation, prefacing the subject with a chapter on current standards. The final part explores opportunities for industrial applications, with chapters on packing, agriculture and biodegradable polycaprolactone foams in supercritical carbon dioxide. Biodegradable polymers for industrial applications explores the fundamental concepts concerning the development of biodegradable polymers, degradable polymers from sustainable sources, degradation and properties and industrial applications. It is an authoritative book that will be invaluable for academics, researchers and policy makers in the industry.

Download or read book Natural Polymers and Biopolymers II written by Sylvain Caillol and published by MDPI. This book was released on 2021-05-05 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: BioPolymers could be either natural polymers – polymer naturally occurring in Nature, such as cellulose or starch…, or biobased polymers that are artificially synthesized from natural resources. Since the late 1990s, the polymer industry has faced two serious problems: global warming and anticipation of limitation to the access to fossil resources. One solution consists in the use of sustainable resources instead of fossil-based resources. Hence, biomass feedstocks are a promising resource and biopolymers are one of the most dynamic polymer area. Additionally, biodegradability is a special functionality conferred to a material, bio-based or not. Very recently, facing the awareness of the volumes of plastic wastes, biodegradable polymers are gaining increasing attention from the market and industrial community. This special issue of Molecules deals with the current scientific and industrial challenges of Natural and Biobased Polymers, through the access of new biobased monomers, improved thermo-mechanical properties, and by substitution of harmful substances. This themed issue can be considered as collection of highlights within the field of Natural Polymers and Biobased Polymers which clearly demonstrate the increased interest in this field. We hope that this will inspire researchers to further develop this area and thus contribute to futures more sustainable society.”
