US Patent:

20100168334, Jul 1, 2010
Filed:

Dec 29, 2008
Appl. No.:

12/345525
Inventors:

Olga Khabashesku - Houston TX, US
Assignee:

FINA TECHNOLOGY, INC. - Houston TX
International Classification:

C08L 51/04
US Classification:

525 86
Abstract:

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.
