摘要: -Iminophosphonamide ligated lanthanum bis(benzyl) complex (NPNDipp)La(CH2Ph-4-Me)2(THF)(NPNDipp=Ph2P(NC6H3iPr2-2,6)2), upon activation of AlEt3 and [Ph3C][B(C6F5)4], exhibited high catalytic activity and high trans-1,4 stereoselectivity for the polymerization of bio-sourced -myrcene (MY). Based on which, a series of novel trans-1,4 regulated elastomers could be generated by random/block copolymerization of MY and isoprene (IP).
