Abstract:
A polymer composition comprises (a) least 40 wt % (based upon the weight of the composition) of a cyclic olefin polymer comprising at least one acyclic olefin and at least 20 wt % of one or more cyclic olefins (based upon the weight of the cyclic olefin polymer), wherein at least a portion of the cyclic olefin polymer has a glass transition temperature of greater than 100° C. ; (b) an acyclic olefin polymer modifier in an amount up to 40 wt % (based upon the weight of the composition); and (c) at least 10 wt % (based upon the weight of the composition) of one of more fillers. The polymer composition has a notched Izod impact resistance measured at 23° C. of greater than 100 J/m and a flexural modulus (1% secant method) of greater than 1400 MPa.
