众所周知，聚烯烃、苯乙烯聚合物和工程塑料占据了塑料市场的最大份额，占世界塑料的近80%。然而，这些塑料通常以混合状态使用或回收，彼此不混溶。很难分别将这些塑料与回收材料进行定义或区分。本文研制了一种接枝聚[苯乙烯-b-（乙烯-共丁烯）-b-苯乙烯]（SEBS）的马来酸酐（MAH）和苯乙烯（St）双单体，SEBS-g-(MAH-co-St)作为工程塑料、苯乙烯聚合物和聚烯烃的多功能相容剂。在增容剂的作用下，模型共混物PA6/PS/PP/ SEBS（70/10/10/10 /10）由脆性向韧性转变，形貌可控，力学性能显著提高。这种高效的增容策略为高性能多相聚合物共混物的开发和废塑料的回收利用提供了新的思路。(C) 2017 Elsevier Ltd.版权所有。
It is well known that polyolefins, styrene polymers and engineering plastics occupy the largest share of the plastic market and constitute nearly 80% of the world's plastic. However, these plastics are usually used or recycled in mixed state and immiscible with each other. It is hard to define or separate these plastics, respectively, from recycled materials. In this letter, a maleic anhydride (MAH) and styrene (St) dual monomers grafted poly [styrene-b-(ethylene-co-butylene)-b-styrene] (SEBS), SEBS-g-(MAH-co-St) was developed as a multi-functionalized compatibilizer for combining engineering plastics, styrene polymers and polyolefins. With the help of the compatibilizer, the model quaternary blend PA6/PS/PP/ SEBS (70/10/10/10) transforms from brittle into tough blends, and shows controllable morphologies and significantly improved mechanical properties. This highly efficient compatibilization strategy casts new light on both the development of high-performance multi-phase polymer blends and the recycling of waste plastics. (C) 2017 Elsevier Ltd.
