The polymerization of bio-renewable myrcene (MY), using a cationic β-diimidosulfonate lutetium catalyst in high activity, afforded an unprecedented isotactic 3,4-polymyrcene (PMY) with a low Tg (-42 °C). Based on this result, the random and block copolymerization of myrcene and isoprene (IP) resulted in novel elastomers that comprise the amorphous iso-3,4-PMY and iso-3,4-PIP sequences.
使用具有高活性的阳离子β-二亚胺磺酸镥催化剂，生物可再生月桂烯（MY）发生聚合反应，得到了一种前所未有的等规3,4-聚月桂烯（PMY），其玻璃化转变温度较低（-42°C）。基于这一结果，月桂烯与异戊二烯（IP）的无规共聚和嵌段共聚产生了新型弹性体，该弹性体包含无定形的异-3,4-PMY和异-3,4-PIP序列。
