Herein, the synthesis of polyethylene via an innovative post-polymerization modification (PPM) approach is reported. For this, a block copolymer of poly[-(acryloyloxy)phthalimide] (PAP) is synthesized by straightforward reversible addition-fragmentation chain-transfer (RAFT) polymerization using a dedicated macroRAFT transfer agent. Upon decarboxylation of the PAP block, followed by efficient block copolymer cleavage, a polyethylene homopolymer with a predictable degree of polymerization is obtained.
本文报道了一种通过创新的聚合后修饰(PPM)方法合成聚乙烯的方法。为此,通过使用专用的大分子 RAFT 转移剂,通过简单的可逆加成-断裂链转移(RAFT)聚合合成了聚[-(丙烯酰氧基)邻苯二甲酰亚胺](PAP)的嵌段共聚物。在 PAP 嵌段脱羧后,通过有效的嵌段共聚物裂解,得到了具有可预测聚合度的聚乙烯均聚物。
