摘要
将刚棒状ＰＢＴ（聚苯撑苯并二噻唑）与含Ｖ型结构ＰＢＴ溶解于稀溶液中，使其在急冷，等温状态下结晶。对生成的结晶体运用透过型电子显微镜等测试手段进行了结构分析比较，结果表明Ｖ型结构ＰＢＴ在稀溶液中结晶时，其分枝结晶部分被排除在主晶体外，形成分枝状结晶。
Rigid rod PBT and
V shaped PBT were dissolved in sulfuric acid and then crystallized. The morphological structure
of the crystallines were determined and analysed using transmission electronic microscopy
(TEM). The result shows that when V shaped PBT is crystallized from its dilute solution the branch
is crystallized outside the crystallized formed by main chain.
