摘　　要：采用水相悬浮接枝的方法合成了线型低密度聚乙烯(LLDPE)与马来酸酐(MAH)、苯乙烯(St)、丙烯酸丁酯(BA)三单体接枝共聚物(LLDPE-g-MSB),研究了合成条件对接枝率的影响,并利用傅里叶变换红外光谱对接枝共聚物进行了表征。结果表明:各单体均参加了接枝反应;将接枝物加入聚氯乙烯(PVC)/木粉复合材料,可提高其力学性能。The ternary-monomer graft copolymers of LLDPE-g-MSB with LLDPE, MAH, St and BA were synthesized by means of water suspension graft method. The effect of the synthesis condition on the graft degree was discussed and analyzed by FTIR. The results show that all monomers participate in the reaction and mechanical properties of PVC wood plastic composites improve with the addition of copolymers.
