Abstract
The influence of casting conditions (solvent and temperature) on the structure of poly(γ-benzyl-L-glutamate) was investigated. From X-ray diffraction analysis and dynamic mechanical, thermal, and dilatometric measurements, it was found that from 1,2-dichloroethane—benzene solutions containing less than 60-% benzene form C proposed by McKinnon and Tobolsky was cast at room temperature and from more than 80-% benzene form A was prepared. The results of casting temperature studies showed that films cast at temperatures below 40°C from dimethylformamide or benzene solution had the structure of form A and films cast above 50°C had the structure of form B.
