Preparation process of modified degradable PE material

The invention discloses a preparation process of a modified degradable PE material, and relates to the technical field of high polymer materials. When the modified degradable PE material is prepared, diethylene glycol and 2-bromo-1, 1-dimethoxyethane are subjected to a reaction, hydrogen bromide is removed to prepare a degradable monomer, and the degradable monomer is embedded in the ethylene polymerization process to prepare the modified degradable PE material. The modified degradable PE material prepared by the invention has good degradability, the process is simple, and industrial production is easy. 本发明公开了改性可降解PE材料的制备工艺，涉及高分子材料技术领域。本发明在制备的改性可降解PE材料时，先将二甘醇、2-溴-1,1-二甲氧基乙烷反应后，再消去溴化氢制得可降解单体，在乙烯聚合过程中嵌入可降解单体制得改性可降解PE材料。本发明制备的改性可降解PE材料具有良好的可降解性能，且工艺简单，易工业化生产。
