| 摘要 |
A rubber-modified polymeric composition having predominately core-shell morphology is disclosed. The rubber-modified polymeric composition can be a polystyrene comprising styrene, polybutadiene, and a high-grafting initiator formed by contacting singlet oxygen with an olefin containing an allylic hydrogen or a diene to form a hydroperoxide or peroxide. The singlet oxygen can be formed by contacting ground state oxygen with a photo catalyst, such a photosensitive dye exposed to light.
