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.

US Classification:

525240

Abstract:

A polymer composition comprises (a) greater than 50 wt % (based upon the weight of the composition) of a cyclic olefin copolymer comprising at least one acyclic olefin and at least 20 weight % of one or more cyclic olefins (based upon the weight of the cyclic olefin copolymer), wherein at least a portion of the cyclic olefin copolymer has a glass transition temperature of greater than 150 C.; and (b) less than 50 wt % (based upon the weight of the composition) of an acyclic olefin polymer modifier, at least a portion of the modifier having a glass transition temperature of less than −30 C.; and no portion of the modifier having a softening point greater than +30 C., wherein the Bicerano solubility parameter of the modifier being no more than 0.6 J/cmless than the Bicerano solubility parameter of the cyclic olefin copolymer. The polymer composition has a notched Izod impact resistance measured at 23 C. of greater than 500 J/m and a heat distortion temperature measured using a 0.46 MPa load of greater than 135 C.

Abstract:

Provided are selected types of terpolymer components comprising terpolymers having monomer units derived from ethylene (E), dicyclopentadiene (DCPD) and norbornene-based (NB) co-monomers. Such terpolymer components have certain specified amounts of each co-monomer as well as certain specified molecular weight and glass transition temperature characteristics. Terpolymer components which are derivatized by hydrogenation and/or by epoxidation and/or hydroxylation are also disclosed, as well as thermoplastic polyolefin compositions which contain the terpolymer components and which have especially desirable structural and thermal properties.Also provided are processes for preparing and derivatizing the terpolymer components herein. Such preparation processes comprise: a) contacting ethylene with a polymerization mixture comprising selected amounts of both DCPD and NB co-monomers, in the presence of a selected activated cyclopentadienyl-fluorenyl metallocene catalyst under specific polymerization conditions to thereby form the desired ethylene-dicyclopentadiene-norbornene terpolymer components within the polymerization mixture. These terpolymer components can then be subsequently derivatized by hydrogenation or functionalization of the residual double bonds therein.
