Abstract
Isoprene chain shuttling polymerisation between the 1,4-trans regulating CpLa(BH)(THF)/MgBuEt (Cp = CMe) and the 1,4-cis regulating NdCl(THF)/AlR (R = Et or Bu) systems provides access to stereoblock polyisoprene. Under selected experimental conditions, the trans segments are semi-crystalline, leading to a thermoplastic elastomer-like material.
摘要
异戊二烯在1,4-反式调节的CpLa(BH)(THF)/MgBuEt（Cp = CMe）和1,4-顺式调节的NdCl(THF)/AlR（R = Et或Bu）体系之间的链穿梭聚合反应可制得立构嵌段聚异戊二烯。在特定实验条件下，反式链段为半结晶态，从而形成一种类似热塑性弹性体的材料。
