反1,4-链节含量接近100％的聚异戊二烯(TPI)具有天然杜仲胶或古塔胶的结构和性能,结晶熔点60—65℃,被认为是作为形状记忆功能材料,如医用矫形材料、各种温敏变形材料的最理想聚合物。关于TPI的合成路线,国外报道主要有V体系(VCl_3/AlEt_3及其负载改性型)和V-Ti混合体系(VCl_3/β-TiCl_3/AlEt_3和Ti(OR)_4/
Polyisoprene (TPI), which has an inverse 1,4-link content close to 100%, has the structure and properties of natural Eucomicum or Gutta gum with a crystalline melting point of 60-65 ° C and is considered as a material for shape memory functions such as Medical orthopedic materials, a variety of temperature-sensitive deformation of the material ideal polymer. As for the synthetic route of TPI, there are mainly reports of V system (VCl_3 / AlEt_3 and its load-modified type) and V-Ti mixed system (VCl_3 / β-TiCl_3 / AlEt_3 and Ti (OR)
