| 摘 要： | 利用熔融接枝法制备了马来酸酐接枝苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS-g-MAH)、马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH),研究了两种接枝共聚物的接枝率及其用量对线型低密度聚乙烯(LLDPE)共混体系黏结性能的影响,并探讨了接枝物的作用机理。结果表明:随着接枝共聚物接枝率和用量的增加,LLDPE/SEBS-g-MAH共混物的黏结性能呈上升趋势;在LLDPE/SEBS-g-MAH共混物中加入POE-g-MAH,可在保证共混物黏结性能的基础上降低SEBS-g-MAH用量,当吸光比为0.1378的POE-g-MAH用量为15%时,体系的拉伸剪切强度达到5.52 MPa;当接枝物用量过高时,接枝物富集区与贫乏区之间的分子链缠结作用减弱导,致黏结性能下降。
