【摘要】 <正>光敏性树形聚合物是一种新型智能高分子材料,聚合物独特的三维结构给材料光敏性能带来的巨大影响引起了人们的广泛关注。高枝化聚合物是继树枝状聚合物和超支化聚合物之后的一类新型树形聚合物,由于其兼具树枝状聚合物结构规整和超支化聚合物合成简便的优势而具有极大的功能化价值。本文结合活性阴离子聚合技术和"点击"化学方法合成了两类光敏性高枝化聚丁二烯,系统考察了聚合物的高枝化结构对材料光敏性能的影响。合成了0-3代含叠氮基团的线形梳状及星形梳状高枝化聚丁二烯,其中第三代高枝化聚丁更多还原

【Abstract】 Photosensitive dendritic polymers are a new class of smart polymer materials,the unique three-dimensional structure of polymer backbones have a big impact on the photosensitive material properties and have been drew more and more attention.Dendrigraft polymers are a new class of dendritic polymers after dendrimer and hyperbranched polymers.Due to their regular controllable structures and convenient synthesis,dendrigraft polymers have a great advantage of functional value.In this paper,it combined the anionic polymerization techniques and "click" chemistry to synthesize two kinds of photosensitive dendrigraft polybutadiene and the effect of dendrigraft architecuture on photosensitive material properties were systematically investigated.更多还原
