Microcrystallization of Atactic Polystyrene Induced by Photooxidation Aging

Macromolecular Materials and Engineering, 2023
Photooxidation aging, hygrothermal aging, and hot‐air aging are carried out on atactic polystyrene (aPS) samples formed by injection molding. It is interesting that microcrystals of atactic polystyrene are only found in photooxidation aging.
