| 摘 要： | 该文以半连续种子乳液聚合工艺合成了一种应用于麦秸/回收低密度聚乙烯（LDPE）复合材料的新型偶联剂——羟基丙烯酸酯共聚物，研究了聚合温度、引发体系对单体转化率及聚合反应稳定性的影响及合成的共聚物与复合材料性能间的关系.研究表明:同时引入较高比例的功能性官能团单体N 羟甲基丙稀酰胺（NMA）和丙烯酸 β 羟乙酯（HEA），用K2S2O8或K2S2O8/FeSO4热引发聚合，近100％的单体转化率和无凝胶的乳液聚合不可兼得；使用助还原剂NaSO2的K2S2O8/FeSO4引发体系，单体转化率可接近100％，而且乳液的综合性能好.将合成的羟基丙烯酸酯共聚物与异氰酸酯PAPI复合偶联麦秸/回收LDPE复合材料，其物理及力学性能提高显著，达到GB/T4897-7—2003规定的在潮湿状态下使用的增强结构用板要求.

| Abstract: | Hydroxied acrylate copolymers, a new type of coupling agent applied wheat straw/recycled low density polyethene(LDPE) composites, was synthesized by the process of semi-continuous seed polymerization of emulsion. The effects of polymerizing temperature，initiator system on monomer conversation ratios and reactive stability，the relationship between acrylate copolymers synthesized and the properties of composites manufactured were investigated. The results show that it is impossible to introduce high proportional N-hydroxymethyl acrylamide（NMA）and βhydroxyl ethyl acrylate （HEA）at the same time，and achieve close 100% monomers conversion ratios and stable copolymerization of no gel with K2S2O8 or K2S2O8/FeSO4 as initiators. While they can implement to use K2S2O8/FeSO4/NaSO2 as initiators. When hydroxied acrylate copolymers synthesized and isocyanate PAPI mixed and used in wheat straw/recycled LDPE composites，the physical and mechanical properties of the composites improved significantly and achieved the standard requirement GB/T4897-7—2003 for heavy-duty load-bearing boards for use in humid conditions. |
