  • Patent number: 9006314
    Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of thermoset polymer particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.

  • Patent number: 9006343
    Abstract: Disclosed is the preparation of compositions which are blends of certain types of hydrogenated ethylene-dicyclopentadiene (E/DCPD) copolymers in combination with elastomeric polymers. An E/DCPD copolymer and an elastomeric polymer are co-dissolved in a common liquid reaction medium which is then subjected to hydrogenation conditions. These hydrogenation conditions serve to hydrogenate in-situ at least a portion of the residual double bonds of the E/DCPD copolymer component and possibly also eliminate any residual unsaturation which might be present in the elastomeric polymers. This combination of materials which has been hydrogenated in-situ can then be co-precipitated to form a polymer composition which can be molded into polyolefin materials of improved structural, thermal and mechanical properties with desirable impact resistance.
