Abstract:
1. A polymer composition comprising a blend comprising (a) about 76 wt % (based upon the weight of the composition) of an amorphous cyclic olefin polymer having a T i) copolymers comprising at least one acyclic olefin and at least 20 mole ° A, of one or more cyclic olefins; (b) about 19 wt % (based upon the weight of the composition) of an acyclic olefin polymer modifier having a glass transition temperature of less than −40° C. wherein said acyclic olefin polymer comprises an elastomeric olefin/nonconjugated diene copolymer comprising an ethylene component, a propylene component and a nonconjugated diene component selected from the group consisting of norbornene ethylidene norbornene (ENB) vinyl norbornene (VNB), and alkyl norbornene; and (c) about 5 wt % (based upon the weight of the composition) a non-functionalized plasticizer having a kinematic viscosity at 100° C. of 10 to 40 cSt, a viscosity index of 130 to 150, a pour point of −48° C. or less and a flash point of 230° C. or more wherein the non-functionalized plasticizer is a polyalphaolefin having an M wherein the polymer composition has a −18° C. Izod Impact (forward notch) of from 42.7 to 64.9 J/m.
