Abstract
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 (<i>T</i><sub>g</sub>) of the resulted COC can be controlled easily by adjusting the feed ratio of the EHBMA and PP. The <i>T</i><sub>g</sub> can be adjusted from 170 to 220℃. The DSC and UV-Vis spectra results show that the <i>T</i><sub>g</sub> and transmittance are up to 220℃ and 92% respectively. The synthesized COC has a <i>T</i><sub>g</sub> about 40℃ higher than t...
