Problems solved by technology

[0010] At present, dicyclopentadiene is sold on the market through the catalysis of tungsten and molybdenum; there is no related product in the market of dicyclopentadiene through ruthenium catalysis; at the same time, dicyclopentadiene single-material polymers are also sold on the market, but bicyclopentadiene Alloys of pentadiene and polymer elastomers have no
METTON in the United States and PENTAM / TELENE in Japan have related primary products, but they are all products formed by the catalysis of dicyclopentadiene, tungsten and molybdenum, and there is no such product in China

Abstract

The invention discloses a polydicyclopentadiene/high-polymer elastomer IPN (interpenetrating polymer network) high-polymer alloy material and a preparation method thereof. The high-polymer alloy material is an interpenetrating network structure formed by the polydicyclopentadiene-formed molecular chain network and the elastomer. The preparation method comprises the following steps: dissolving the elastomer in a dicyclopentadiene liquid; and adding a catalyst into the elastomer dicyclopentadiene solution, injecting the mixed solution into a mold, and curing by reaction. The high-polymer elastomer is completely dissolved to form the uniform continuous phase, and the elastomer also forms the network structure while the dicyclopentadiene molecular chain forms the network structure, thereby forming the dicyclopentadiene-elastomer-interpenetrating IPN high-polymer alloy material. The high-polymer alloy material has the rigidity of the dicyclopentadiene, and also has favorable toughness.

Description

technical field [0001] The invention relates to an IPN polymer alloy material of polydicyclopentadiene / polymer elastomer, which belongs to the technical field of catalysts. Background technique [0002] In the existing toughened modified polydicyclopentadiene materials, the elastomer used for toughening during the preparation process cannot be completely dissolved, that is, in a semi-dissolved state, so that it is prone to precipitation and stratification when preparing products. The elastomer forms isolated islands in the grid of the molecular chain network of polydicyclopentadiene. [0003] IPN (Interpenetrating Polymer Network): Interpenetrating polymer network structure is a network structure formed by two or more blended polymers, the molecular chains of which interpenetrate each other, and at least one polymer molecular chain is cross-linked by chemical bonds. In 1914, Aylsworth first made IPN structure polymer from natural rubber, sulfur and partially reacted phenol ...
