Optically isotropic blends of styrene/acrylonitrile and methyl methacrylate/glutarimide copolymers |
abstract |
Optically isotropic blends comprising styrene/acrylonitrile copolymers containing from 18 to 32 percent acrylonitrile and methyl methacrylate/glutarimide resins containing from 10 to 50 weight percent methyl methacrylate and having stress optical coefficient of between -500 Brewsters and +500 Brewsters are usefully employed in the preparation of molded objects having reduced birefringence. |
