A method of creating a modified heterophasic polyolefin composition is provided, whereby a polyolefin composition having at least two phases is melt mixed with a free radical generator, such as a peroxide, and a compatibilizing agent characterized by at least one nitroxide radical and at least one unsaturated bond capable of undergoing a radical addition reaction. Modified heterophasic polyolefin compositions with increased melt flow rates, impact strength, and clarity, which incorporate the compatibilizing agent, are also included within the scope of the invention.
本发明提供了一种制造改性杂相聚烯烃组合物的方法,即把至少有两相的聚烯烃组合物与自由基发生器(如过氧化物)和相容剂熔融混合,相容剂的特征是至少有一个亚硝基自由基和至少有一个不饱和键能发生自由基加成反应。本发明的范围还包括含有相容剂的改性杂相聚烯烃组合物,这种组合物具有更高的熔体流动速率、冲击强度和透明度。
