Title:
POLY(ETHYLENE-ALIPHATIC DIENE)-G-POLYSTYRENE BASED COPOLYMER HAVING IMPROVED MECHANICAL PROPERTIES AND HEAT RESISTANCE AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2015/023047
Kind Code:
A1
Abstract:
The present invention relates to a poly(ethylene-aliphatic diene)-g-polystyrene based copolymer having improved physical properties and heat resistance and a method for preparing the same and, more specifically, to a poly(ethylene-aliphatic diene)-g-polystyrene based copolymer which has an ethylene-aliphatic diene copolymer as a soft segment and a polystyrene based polymer as a hard segment grafted onto the soft segment, and to a method for preparing the same. The poly(ethylene-aliphatic diene)-g-polystyrene based copolymer has equal elasticity to SBS or SEBS and improved heat resistance and mechanical properties such as tensile strength, and thus can substitute therefor.
