β-Myrcene was polymerized with catalysts based on pyridyl-imino complexes of neodymium, iron and copper. Highly stereoregular polymers were obtained: in particular, the neodymium-based catalyst gave highly cis-1,4 polymers (≥97%), while iron and copper catalysts gave a quite unusual structure in the field of stereospecific polymerization, that is, a predominantly alternating cis-1,4-alt-3,4 polymer containing cis-1,4 unit (five units) sequences within the polymer chain. Structural, thermal and mechanical characterization of the obtained polymers was carried out.

使用钕基、铁基和铜基催化剂合成有规立构聚月桂烯

β-月桂烯是用基于钕、铁和铜的吡啶基亚氨基配合物的催化剂聚合而成的。获得了高度有规立构的聚合物：特别是，基于钕的催化剂得到了高度顺式的-1,4聚合物（≥97％），而铁和铜催化剂则在立体有择聚合领域给出了非常不寻常的结构，即主要是聚合物链内含有顺式-1,4-交替-3,4单元（五个单元）序列的交替聚合物。对所得聚合物进行了结构、热和机械表征。
