已知,聚异戊二烯或聚丁二烯等1,3-双烯聚合物可在路易斯酸催化剂作用下按阳离子型机理进行分子内环化反应,所得“环化橡胶”,做为可光敏固化的新材料,在光刻胶、光保护膜、胶粘剂等方面得到广泛应用。文献还表明,环化顺1,4聚双烯产物比环化其它结构的聚双烯产物具更好的使用性能。鉴于合成高分子材料中共聚物往往较均聚物呈现 It is known that a 1,3-diene polymer such as polyisoprene or polybutadiene can be subjected to an intramolecular cyclization reaction by a cationic mechanism under the action of a Lewis acid catalyst. The resulting “cyclized rubber” Photosensitive curing of new materials, in the photoresist, light protection film, adhesives, etc. are widely used. The literature also shows that the cyclized cis-1,4-diolefin product has better performance properties than cyclization of other structures. Given the fact that copolymers in synthetic polymer materials tend to be more homogeneous than homopolymers
