Abstract

The invention discloses a polytricyclopentadiene (PTCPD) high polymer material as well as a preparation method and application thereof. The high polymer material is prepared from the following components: tricyclopentadiene (TCPD) and a catalyst; wherein the weight percentage of tricyclopentadiene TCPD is greater than or equal to 50% and less than 100%. As TCPD is large in molecular weight and rigidity, the rigidity of the prepared PTCPD high polymer material is far greater than that of the existing polydicyclopentadiene high polymer material, and the technical problem of insufficient rigidity of the polydicyclopentadiene material in the prior art is solved. Meanwhile, the PTCPD high polymer material also has excellent characteristics of acid resistance, alkali resistance, seawater corrosion resistance, fatigue resistance and the like, and is suitable for the fields of vehicles, ships, chemical pipelines and containers, sewage treatment tanks, medical equipment, sports entertainment equipment, sanitary products, wind power blades, fan impellers, deep sea aquaculture net equipment and the like.
