我们报告了一种新的和有效的策略，增容三个不混溶的聚合物，聚烯烃，苯乙烯聚合物，和工程塑料，通过使用聚烯烃基多相增容剂实现。研究了马来酸酐（MAH）和苯乙烯（St）双单体熔融接枝聚丙烯（PP）制备的多相增容剂（PP-g-（MAH-co-St））对聚丙烯（PP）/聚苯乙烯（PS）/聚酰胺（PA 6）三元不混溶聚合物模型共混物的增容效果和形态结构的影响。扫描电子显微镜（SEM）结果表明，PP-g-（MAH-co-St）作为多相增容剂对PP/PS/PA 6共混体系具有较好的增容作用。多相增容剂的加入使PS和PA 6的粒径大大减小，同时提高了不互溶对的界面粘结力。这种良好的增容效果是有希望的开发一种新的，技术上有吸引力的方法，用于实现不相容的多组分聚合物共混物的增容，以及回收和再利用这样的共混物。PP/PS/PA 6（70/15/15）非增容共混物的相形态研究表明，共混物是由PS相包裹PA 6核的复合液滴分散在PP基体中构成的。而增容后的共混物中，三种组分之间存在强烈的相互作用，即多相增容剂对不同的不相容对具有良好的增容作用。对于40/30/30共混物，形态从三相共连续形态（未增容）变为PA 6和PS在PP基体中的分散液滴（增容）。
We report a novel and effective strategy that compatibilizes three immiscible polymers, polyolefins, styrene polymers, and engineering plastics, achieved by using a polyolefin-based multi-phase compatibilizer. Compatibilizing effect and morphology development are investigated in a model ternary immiscible polymer blends consisting of polypropylene (PP)/polystyrene(PS)/polyamide(PA6) and a multi-phase compatibilizer (PP-g-(MAH-co-St) as prepared by maleic anhydride (MAH) and styrene (St) dual monomers melt grafting PP. Scanning electron microscopy (SEM) results indicate that, as a multi-phase compatibilizer, PP-g-(MAH-co-St) shows effective compatibilization in the PP/PS/PA6 blends. The particle size of both PS and PA6 is greatly decreased due to the addition of multi-phase compatibilizer, while the interfacial adhesion in immiscible pairs is increased. This good compatibilizing effect is promising for developing a new, technologically attractive method for achieving compatibilization of immiscible multi-component polymer blends as well as for recycling and reusing of such blends. For phase morphology development, the morphology of PP/PS/PA6 (70/15/15) uncompatibilized blend reveals that the blend is constituted from PP matrix in which are dispersed composite droplets of PA6 core encapsulated by PS phase. Whereas, the compatibilized blend shows the three components strongly interact with each other, i.e. multi-phase compatibilizer has good compatibilization between the various immiscible pairs. For the 40/30/30 blend, the morphology changed from a three-phase co-continuous morphology (uncompatibilized) to the dispersed droplets of PA6 and PS in the PP matrix (compatibilized).
