The present invention relates to expandable, polymerizable compositions comprising at least one benzoxazine and at least one cyclic carbonate, to polymerization products of these expandable, polymerizable compositions, to a process for preparing these polymerization products as well as to uses of these expandable, polymerizable compositions. The present invention is based on the surprising finding that copolymerizing benzoxazine monomers with cyclic carbonate monomers results in novel copolymers having unforeseeably high expansion rates, wherein the properties (e.g. solid/brittle, solid/soft, rubbery) of the resulting copolymers can be easily and reproducibly tuned/adjusted, depending on the ratio of the benzoxazine equivalents/cyclic carbonate equivalents present in the composition and copolymer, respectively.
本发明涉及可膨胀、可聚合的组合物,包括至少一种苯并噁嗪和至少一种环状碳酸酯,以及这些可膨胀、可聚合的组合物的聚合产物、制备这些聚合产物的方法以及使用这些可膨胀、可聚合的组合物的用途。本发明基于一个令人惊讶的发现,即将苯并噁嗪单体与环状碳酸酯单体共聚合可产生新颖的共聚物,其膨胀速率高得难以预见,所得共聚物的性质(例如固体/脆性、固体/柔性、橡胶状)可以根据组合物和共聚物中苯并噁嗪当量/环状碳酸酯当量的比例轻松和可重复地调节/调整。
