Abstract
The structural characteristics observed in copoly(γ-methyl, benzyl L-glutamate)s as a result of a systematic change in the side-chain composition have been classified for films cast from different solvents. The packing structures were seen to vary significantly as a function of the casting solvent, as well as the benzyl content in the copolymer. With the side-chain composition near the two extremes, the packing structures observed were similar to those of the corresponding homopolymers. However, in the intermediate region, characteristically different packings were discovered. For films cast from the N,N-dimethylforrnamide type of solvents, a well defined packing distorted from tetragonal packing, and in the case of the chloroform type of solvents a tetragonal-like molecular packing, were observed. These packings are discussed in the light of various factors influencing the molecular structures of solid films.
