A process to form an ethylene-based polymer including polymerizing ethylene and at least one asymmetrical polyene comprising an “alpha, beta unsaturated-carbonyl end” (“α,β unsaturated-carbonyl end”) and a “C—C double bond end,” wherein the polymerization takes place in the presence of at least one free-radical initiator; and wherein the polymerization takes place in a reactor configuration comprising at least two reaction zones, reaction zone 1 and reaction zone i (i≥2), wherein reaction zone i is downstream from reaction zone 1.
一种形成乙烯基聚合物的工艺,包括使乙烯和至少一种不对称聚烯聚合,该不对称聚烯包括 "α、β不饱和羰基端"("α、β不饱和羰基端")和 "C-C双键端",其中聚合在至少一种自由基引发剂存在下进行;聚合在反应器配置中进行,反应器配置包括至少两个反应区,即反应区1和反应区i(i≥2),其中反应区i位于反应区1的下游。
