ABSTRACT In this work, the systematic investigation of the influence of two compatibilizers added individually or together in 80/20 (wt/wt) polypropylene (PP)/acrylonitrile butadiene styrene (ABS) blends in the presence of carbon black (CB) are investigated. The compatibilizers used are PP-grafted maleic anhydride (PP-g-MA) and styrene-ethylene, butylene-styrene–grafted maleic anhydride (SEBS-g-MA). All the composition shows the formation of matrix-droplet morphology. The addition of both PP-g-MA and SEBS-g-MA in 80/20 (wt/wt) PP/ABS blends refines the morphology significantly as compared to 80/20 (wt/wt) PP/ABS blend in presence and absence of PP-g-MA and SEBS-g-MA individually. The average droplet diameter and interparticle distance of all the compositions were measured and correlated with crystallinity and mechanical properties of CB-filled and PP-g-MA/SEBS-g-MA-compatibilized 80/20 (wt/wt) PP/ABS blends. In addition, crystalline behaviour is correlated with the mechanical properties of CB-filled and PP-g-MA/SEBS-g-MA-compatibilized 80/20 (wt/wt) PP/ABS blends. The addition of CB up to 5 wt.% in both PP-g-MA and SEBS-g-MA in 80/20 (wt/wt) PP/ABS blends refines the morphology significantly as compared to 80/20 (wt/wt) PP/ABS blend in presence and absence of PP-g-MA and SEBS-g-MA individually. Solution experiments, interfacial tension and free wetting enthalpy calculations were done to understand the localization of CB in one phase of PP/ABS blends. Further, the addition of CB in 80/20 (wt/wt) PP/ABS blends in the presence of PP-g-MA and SEBS-g-MA added individually or together shows improved thermal stability as compared to neat blends.

双相容剂和炭黑对PP/ABS共混物及其复合材料力学和热性能的影响

摘要 在这项工作中，系统研究了两种增容剂在炭黑 (CB) 存在下单独或一起添加到 80/20 (wt/wt) 聚丙烯 (PP)/丙烯腈丁二烯苯乙烯 (ABS) 混合物中的影响. 所用的增容剂是 PP 接枝的马来酸酐 (PP-g-MA) 和苯乙烯-乙烯、丁烯-苯乙烯接枝的马来酸酐 (SEBS-g-MA)。所有的组合物都显示出基质-液滴形态的形成。在 80/20 (wt/wt) PP/ABS 共混物中添加 PP-g-MA 和 SEBS-g-MA 与 80/20 (wt/wt) PP/ABS 共混物存在和分别不存在 PP-g-MA 和 SEBS-g-MA。测量了所有组合物的平均液滴直径和颗粒间距离，并将其与 CB 填充和 PP-g-MA/SEBS-g-MA 相容的 80/20 (wt/wt) PP/ABS 共混物的结晶度和机械性能相关联. 此外，结晶行为与 CB 填充和 PP-g-MA/SEBS-g-MA 相容的 80/20 (wt/wt) PP/ABS 共混物的机械性能相关。与 80/20 (wt/wt) PP/ABS 共混物相比，在 PP-g-MA 和 SEBS-g-MA 中添加高达 5 wt.% 的 CB 显着改善了形态) PP/ABS 在分别存在和不存在 PP-g-MA 和 SEBS-g-MA 的情况下共混。进行溶液实验、界面张力和自由润湿焓计算以了解 CB 在 PP/ABS 共混物的一相中的定位。更多，与纯共混物相比，在 PP-g-MA 和 SEBS-g-MA 单独或一起添加的情况下，在 80/20 (wt/wt) PP/ABS 共混物中添加 CB 显示出改善的热稳定性。图形概要
