高聚物的共混成型可以使其制品获得一些新的性能,满足使用方面的某些特殊要求。但是,要使不同种类的高聚物能在一定条件或状态下互溶或近似互溶,往往需要有合适的分散剂。为了解决聚丙烯树脂和聚酯树脂、聚酰胺树脂等的共混成型,实现聚丙烯树脂、纤维、塑料等方面产品改性,我们研究和开发了一种高分子量的聚丙烯改性剂PCT,从而制得了低温成型及中温成型的可染性树脂新品种,制得了性能良好的可染性 Blended polymer can make its products to obtain some new performance, to meet the use of certain special requirements. However, to allow different types of polymers to be miscible or nearly miscible under certain conditions or conditions, a suitable dispersant is often required. In order to solve the polypropylene resin and polyester resin, polyamide resin blending molding, to achieve polypropylene resin, fiber, plastic and other aspects of product modification, we have studied and developed a high molecular weight polypropylene modifier PCT, Thereby producing a low-temperature molding and temperature molding of new varieties of dyeable resin, prepared with good performance dyeability
