摘　　要：在催化剂的作用下,将乙烯-醋酸乙烯共聚物(EVA)与硼酸三丙酯进行反应,制备得到可回收的EVA类玻璃体并研究其可回收性能。测试结果表明,与纯EVA相比,EVA类玻璃体表现出优异的耐化学稳定性、机械性能和耐候性,经回收利用4次后,杨氏模量仅下降9.8%。Under catalysis,ethylene-vinyl acetate copolymer(EVA)was reacted with tripropyl borate to prepare a recyclable EVA vitrimer,aimed at studying its recyclability,The results show that,compared to thermoplastic pure EVA,the EVA vitrimer exhibits superior chemical stability,mechanical properties,and weather resistance,After four recycling cycles,the Young’s modulus decreased by only 9.8%.
