Document Type and Number:
Japanese Patent JPH0425304
Kind Code:
B2
Abstract:
Incorporation of an ester plasticizer having a solubility parameter from about 7.8 to about 10.2 (cal/cc)1/2 increases the flexibility and impact strength of poly(dicyclopentadiene). In a preferred embodiment of the method for poly(dicyclopentadiene) synthesis, the plasticizer is incorporated into at least one or two parts of a metathesis-catalyst system: a catalyst/monomer solution or an activator/monomer solution. The two parts are then combined in the mixing head of a reaction injection molding machine and injected into a mold where the reaction mixture rapidly sets up into a thermoset polymer with greater flexibility and impact strength than is found in the corresponding unplasticized poly(dicyclopentadiene).
