A compatible blend of an engineering thermoplastic such as a polyamide and an olefin polymer material is prepared by (1) making an oxidized olefin polymer material containing carboxylic acid groups or derivatives thereof, (2) extruding a mixture of (a) the oxidized olefin polymer material from step (1), (b) an engineering thermoplastic, (c) optionally, an inorganic base, and (d) optionally, a non-oxidized olefin polymer material, and (3) recovering a blend of the engineering thermoplastic, the oxidized olefin polymer material or an ionomer thereof, which acts as a compatibilizer, and, optionally, the non-oxidized olefin polymer material.
The oxidized olefin polymer material can be made by treating the olefin polymer material with an organic peroxide initiator while adding a controlled amount of oxygen.
一种工程热塑性塑料(如聚酰胺)和烯烃聚合物材料的兼容混合物是通过以下步骤制备的:(1)制备含有羧酸基或其衍生物的氧化烯烃聚合物材料,(2)挤出混合物,该混合物包括(a)步骤(1)中的氧化烯烃聚合物材料,(b)工程热塑性塑料,(c)可选的无机碱,以及(d)可选的未氧化的烯烃聚合物材料,(3)回收工程热塑性塑料、氧化烯烃聚合物材料或其离子聚合物(作为相容剂)以及可选的未氧化的烯烃聚合物材料的混合物。氧化烯烃聚合物材料可以通过在添加控制量的氧气的同时使用有机过氧化物引发剂处理烯烃聚合物材料而制备。
