摘要
基于2,6-二甲基吡啶亚胺铁催化体系催化乙烯链穿梭聚合制备端羟基聚乙烯树脂;进行羟基丙烯酸酯的封端反应,赋予聚乙烯树脂紫外光固化活性。研究了改性聚乙烯树脂作为主体树脂及添加助剂应用于光固化涂料配方中进行研究。核磁及红外分析表明,获得两种结构明确的可紫外光固化改性聚乙烯树脂。通过光固化涂料配方研究表明,可紫外光固化聚乙烯树脂的光固化涂层光泽度较低,可作为哑光树脂使用。
A well- defined UV- curable linear polyethylene resin with low molecular weight and end hydroxyl functional was synthesized by chain shuttling ethylene polymerization with 2,6- bis[1-（2,6- diisopropylphenylimino）ethyl] pyridyl iron（ II） dichloride as catalyst and acrylate capped reaction. NMR and IR analysis showed that the two structures obtained were UV curable modified polyethylene resin. As an additive in the UV- curable formulation,the resin can increase the amount matting agent in the formulation in an amount to some extent.
