<p>The invention relates to an impact resistant polymer composition based on a copolymer of unsaturated nitrile, a largely saturated rubber and a chlorinated polyethylene.
<??>To improve certain properties of said composition, it is characterized in that said composition comprises:
a. 50-95 parts by weight of one or more polymers obtained by the polymerizaton of 10-90 % by weight of styrene and/or derivatives of styrene and 90-10 % by weight of acrylonitrile and/or methacrylonitrile.
b. 5-50 parts by weight of
b.1. a largely saturated rubber
b.2. chlorinated polyethylene, which chlorinated polyethylene has a chlorine content of between 32 and 40% by weight and a DSC crystallinity of 0-7 %, while the weight ratio of rubber to chlorinated polyethylene is between 2:1 and 1 : 10. </p> |
