Ig. Silinskaya et al., Structural transformations in concentrated solutions of photosensitive polymers based on polyamido acids, RUS J AP CH, 72(8), 1999, pp. 1433-1437
Using the polarized light scattering method, a comparative study was made,
in terms of the Debye-Stein statistical theory, of the structural changes o
ccurring during storage of concentrated solutions of two polyamido acids ba
sed on 3,3',4,4'-benzophenonetetracarboxylic acid anhydride and 4,4'-diamin
odiphenylmethane, as well as on 3,3',4,4'-diphenyltetracarboxylic acid anhy
dride and 2,5-bis (p-aminophenyl)pyrimidine partly esterified at carboxy gr
oups with glycidyl methacrylate.
