骨架可水解的具核超支化聚缩醛的合成与表征
DOI: 10.3724/SP.J.1105.2013.12302, PP. 391-397
Keywords: 缩醛转移聚合,超支化聚缩醛,骨架可水解
Abstract:
通过AB2型聚合单体4-(2-羟基乙氧基)苯甲醛二甲缩醛与B2型核分子苯甲醛二甲缩醛的缩醛转移聚合反应,反应过程中不断排出低沸点的醇,合成了具核、骨架可水解的超支化聚缩醛(HBPAs).实验表明,HBPAs的分子量,多分散性和聚合度随着核比例的改变发生明显的变化.增加核比例,聚合物的分子量,多分散性和聚合度均降低.HBPAs在弱酸性条件下,骨架发生水解,生成4-(2-羟基乙氧基)-苯甲醛.研究发现,核比例对于聚合物降解速率有明显的影响,增加核比例,聚合物的降解速率加快.这表明,通过加入核分子,可以在一定程度上调控超支化聚缩醛的结构与性能.
