BLENDS OF alpha -OLEFIN/VINYLIDENE AROMATIC MONOMER OR HINDERED ALIPHATIC VINYLIDENE MONOMER INTERPOLYMERS WITH POLYOLEFINS

摘要

Thermoplastic blends are prepared from polymeric materials comprising (A) from 1 to 99 weight percent of at least one interpolymer made from monomer components comprising (1) from 1 to 65 mole percent of (a) at least one aromatic vinylidene monomer, or (b) at least one hindered aliphatic or cycloaliphatic vinylidene monomer, or (c) a combination of at least one aromatic vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinylidene monomer, and (2) from 99 to 35 mole percent of at least one aliphatic alpha -olefin having from 2 to 20 carbon atoms; and (B) from 99 to 1 weight percent of at least one polymer made from monomer components comprising (1) from 1 to 100 mole percent of at least one alpha -olefin having from 2 to 20 carbon atoms, and (2) from 0 to 99 mole percent of at least one alpha -olefin having from 2 to 20 carbon atoms which monomer is different from the monomer of component (B-1). These blends possess improved properties when compared to the properties of the polymers comprising the blend. These blends are useful in the preparation of films, fabricated articles, injection molded parts, bitumen and asphalt modification, hot melt and pressure sensitive adhesive systems.
