Abstract The copolymers of ethylene with the double-decker silsesquioxane (DDSQ) were synthesized by copolymerization with the use of metallocene and bis(phenoxy-imine) catalysts. The influence of the kind of the catalyst and polyreaction conditions on the performance of copolymerization as well as on the properties of the copolymers was studied. Depending on polyreaction parameters, the DDSQ contents in the copolymer varied in the range of 0.93–11.53 wt% which determined the compositions and the structural properties of copolymers. DDSQ incorporated into the polymer chain could constitute pendant groups in the main chain or it could act as a cross-linking agent. The ethylene/DDSQ copolymers also had different kinds and contents of unsaturated end groups and they offered interesting morphological and thermal properties including various glass transition temperatures as well as melting and crystallization behaviours.

通过配位共聚制备含有双层倍半硅氧烷作为侧基和交联位点的乙烯共聚物的合成和结构表征

摘要 在茂金属和双（苯氧基-亚胺）催化剂的作用下，通过共聚反应合成了乙烯与双层倍半硅氧烷（DDSQ）的共聚物。研究了催化剂种类和聚合反应条件对共聚性能和共聚物性能的影响。根据聚合反应参数，共聚物中的 DDSQ 含量在 0.93-11.53 wt% 的范围内变化，这决定了共聚物的组成和结构特性。掺入聚合物链的 DDSQ 可以构成主链中的侧基，也可以作为交联剂。
