This book was released on 1966 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a linear relationship between the molar refraction, R, and the sum of the molar-attraction constants, (sq. rt. of (EV)), both for liquids and polymers. It follows that cohesive energy density, E/V, is directly proportional to the refractive index function, (n sq. - 1/n sq. + 2)sq. It is shown and found that for two non-polar rubbers, swelling tends to increase as the refractive index of a solvent approaches that of a rubber, but maximum swelling occurs at a lower refractive index than predicted. As expected, swelling data for polar rubbers and solvents do not follow the predicted trend. No relationship is found between glass temperature (TG) and refractive index for polymers having TG's below 298K because of divergences in data from relationships involving cohesive energy density and TG and between R and (sq. rt. of (EV)).

This book was released on 1965 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between cohesive energy (c.e.) or cohesive energy density (c.e.d.) and the glass transition temperature T sub G of polymers was re-examined on the basis of literature data. For polymers with T sub G's above 25 C there is no correlation between published or calculated values of c.e. or c.e.d. and T sub G. However, for the rest of the polymers there is a linear relationship between c.e.d. and T sub G, and a broad relationship between c.e. and T sub G. These results imply that c.e.d. is the regulating, though not the only, factor in determining T sub G's up to values of approximately 25 C. (Author).

This book was released on 2018-05-02 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now available for the first time, this valuable reference presents polymer solubility parameters and various polymer-liquid interaction parameters in an easy-to-use form. It critically evaluates and comprehensively compiles data from original sources. It presents these quantities polymer-by-polymer, alphabetically by polymer common chemical name, fully cross-referenced by systematic chemical names, alternative names and trade names. This one-of-a-kind handbook summarizes the relationship between the various quantities and their methods of determination. This resource is an absolute must for all who are interested in the chemical industry, specifically polymer chemistry, chemical engineering, applied chemistry, and physical chemistry.
