以溴化亚铜为催化剂,采用原子转移自由基聚合方法对MMA和乙烯进行共聚合,用核磁共振法表征了共聚物中聚乙烯的含量。结果表明,在压力为6 MPa的条件下,MMA与乙烯共聚物中聚乙烯的摩尔分数可达到15.9%。
Copolymerization of MMA with ethylene using atom transfer radical polymerization was carried out using cuprous bromide as catalyst, and the content of polyethylene in the copolymer was characterized by nuclear magnetic resonance. The results show that the mole fraction of polyethylene in MMA and ethylene can reach 15.9% under the pressure of 6 MPa.
