报道了二炔与单炔在甲苯中以 Cp Co( CO) 2 为催化剂通过一步环三聚反应得到高分子量的超支化聚芳烃 ,以 GPC,NMR和 TGA对所合成的聚合物进行了系统结构和性能表征 ,证明所合成聚合物均具所设计的聚合物结构和有良好的热稳定性
It was reported that diacetylene and monosyne were polymerized by one-step cyclization in toluene with Cp Co (CO) 2 as the catalyst to obtain high molecular weight hyperbranched polyarenes. The synthesized polymers were characterized by GPC, NMR and TGA And characterization of the properties of the synthesized polymers proved to have a designed polymer structure and good thermal stability
