摘要： A polymer composition, e.g. a high-impact polystyrene, having novel morphological structure comprises a polymeric matrix, e.g. polystyrene, in which there are dispersed particles of a second polymer, e.g. an ethylene-propylene terpolymer. The particles of second polymer contain occlusions of matrix polymer and the occlusions also contain sub-occlusions of a third polymeric species, e.g. polybutadiene, which is more specific to grafting with the monomeric constituents of the matrix polymer than is the second polymer species. The compositions are tough and have good oxidation resistance.
