ETHYLENE/ALPHA-OLEFIN COPOLYMER COMPOSITION

摘要

PURPOSE:A copolymer composition of controlled coloration, prepared by adding zinc stearate to an ethylene/alpha-olefin copolymer synthesized according to a specified process. CONSTITUTION:A copolymer composition prepared by adding 100-5,000ppm of zinc stearate to an ethylene/alpha-olefin copolymer synthesized by a high-pressure solventless ion polymerization process. The addition of zinc stearate allows the copolymer composition to show controlled coloration and extremely high resistance to yellowing.
