Abstract

The invention discloses a polytricyclopentadiene PTCPD polymer material and a preparation method and application thereof. The polymer material comprises the following components: tricyclopentadiene TCPD; catalyst; wherein, tricyclopentadiene The weight percentage of alkene TCPD is greater than or equal to 50% and less than 100%. Due to the large molecular weight and high rigidity of TCPD, the rigidity of the prepared PTCPD polymer material is far greater than that of the existing polydicyclopentadiene polymer material, which solves the problem of insufficient rigidity of the polydicyclopentadiene material in the prior art. technical problem. At the same time, PTCPD polymer material also has excellent properties such as acid resistance, alkali resistance, seawater corrosion resistance, fatigue resistance, etc. It is suitable for vehicles, ships, chemical pipelines and containers, sewage treatment tanks, medical equipment, sports and entertainment equipment, sanitary products, wind power blades, Fan impeller, deep sea aquaculture net equipment and other fields.
