Novel high temperature and transparent cyclic olefin copolymers (COC) derived from bulky cyclic olefin {exo-1,4,4a,9,9a,10-hexahydro-9,10(10,20)-benzeno-l,4-methanoanthracene (EHBMA)} were successfully synthesized by the copolymerization of EHBMA and propylene(PP). The glass transition temperature (Tg) of the resulted COC can be controlled easily by adjusting the feed ratio of the EHBMA and PP. The Tg can be adjusted from 170 to 220℃. The DSC and UV-Vis spectra results show that the Tg and transmittance are up to 220℃ and 92% respectively. The synthesized COC has a Tg about 40℃ higher than that of commercial TOPAS 6017 product. The tensile test showes that the COC material has good mechanical properties. The synthesized COC has high thermal stabilities, good mechanical properties and excellent transparencies, and it will be used in the aerospace, medical and other high-tech fields.
