研究了钪催化乙烯与双环戊二烯（DCPD）的共聚合以及乙烯、双环戊二烯和苯乙烯的三元共聚合。乙烯与双环戊二烯的共聚反应可在0-70 ℃的较宽温度范围内进行。在50 ℃时，DPCD掺入量约为100%，催化活性最高. 44摩尔%。结果表明，阳离子半夹心稀土金属烷基配合物作为环（二）烯烃共聚合和三元共聚合的催化剂具有前所未有的潜力。
The scandium-catalyzed copolymerization of ethylene with dicyclopentadiene (DCPD) and terpolymerization of ethylene, DCPD and styrene were investigated. The copolymerization of ethylene with DCPD could be carried out over a wide range of temperatures between 0-70 C. The highest catalytic activity was achieved at 50 C with a DPCD incorporation of ca. 44 mol%. The results show that cationic half-sandwitch rare earth metal alkyl complexes are of unprecedented potentials as a catalysts for copolymerization and terpolymerization of cyclic (di) olefins.
