摘要：

Isoprene chain shuttling polymerisation between the 1,4-trans regulating Cp*La(BH4)(2)(THF)(2)/(MgBuEt)-Bu-n (Cp* = C5Me5) and the 1,4-cis regulating NdCl3(THF)(2)/AlR3 (R = Et or Bu-i) systems provides access to stereoblock polyisoprene. Under selected experimental conditions, the trans segments are semi-crystalline, leading to a thermoplastic elastomer-like material.
