介绍了分别在单催化、双催化体系作用下以环烯烃、链烯烃为原料催化共聚改性聚双环戊二烯(PDCPD)的机理,并综述了不同催化体系对PDCPD共聚改性物的阻燃性,冲击强度、拉伸强度及热稳定性等影响的国内外研究进展。
The mechanism of catalytic copolymerization of polycyclic dicyclopentadiene (PDCPD) with cyclic olefins and alkenes catalyzed by single catalysis and dual catalysis respectively was introduced. The effects of different catalysis systems on the flame retardancy of PDCPD copolymerization modifiers Sexual, impact strength, tensile strength and thermal stability of domestic and foreign research progress.
