Compositions of high impact norbornenos containing policiano

摘要

A blend of 100 parts by weight of a polycyano norbornene, such as poly)2-norbornene-5 nitrile); 5 to 15 parts of a halogenated polyolefin, such as chlorinated polyethylene; and 10 to 40 parts of an ABS polymer, such as acrylonitrile-butadiene-styrene resin. This blend, when formed into a rigid structure, has an unexpectedly higher impact strength.
