POLYPROPYLENE-B-POLY(ETHYLENE-CO-PROPYLENE) AND ITS PRODUCTION

摘要

PURPOSE: To obtain a new polypropylene-b-poly(ethylene-co-propylene) and its production in which a polypropylene is chemically bonded to a poly(ethylene- co-propylene). CONSTITUTION: This polypropylene-b-poly(ethylene-co-propylene) in which a polypropylene is chemically bonded to a poly(ethylene-co-propylene) is obtained by synthesizing a polypropylene in the presence of a carrier type Ziegler catalyst and forming a poly(ethylene-co-propylene) at the end of the polypropylene.
