Linear polyethylenes with a combination of incorporated in-chain keto as well as side-chain ester groups are formed by Ni(II)-catalyzed terpolymerization of ethylene, carbon monoxide, and methyl acrylate. These possess a random structure, with largely isolated nonalternating in-chain keto groups as well as ester-substituted units adjacent to the polyethylene chain, whereas the solid-state structure of polyethylene is retained. Molecular weights of the terpolymers (M_n ∼ 20.000 g mol^–1) are predominantly determined by chain transfer after acrylate incorporation.

来自一氧化碳和丙烯酸酯的催化三元聚合的链内和侧链组合官能团的聚乙烯

结合了链内酮基和侧链酯基的线性聚乙烯是由 Ni(II) 催化的乙烯、一氧化碳和丙烯酸甲酯的三元聚合形成的。它们具有随机结构，具有大量孤立的非交替链内酮基以及与聚乙烯链相邻的酯取代单元，而聚乙烯的固态结构得以保留。三元共聚物的分子量（M _n ∼ 20.000 g mol ^–1）主要由丙烯酸酯结合后的链转移决定。
