摘 要: 考察了共混方法、共混温度、共混时间、共混比等对高聚合度聚氯乙烯(HPVC)/NBR共混体系结构与性能的影响。结果表明,采用二阶共混法可获得最佳共混效果,共混温度宜控制为175~185℃;HPVC/NBR共混体系是宏观相容、微观相分离体系,与普通PVC/NBR共混体系相比。 The influence of the bleding process,temperature,cycle and ratio on the structure and properties of HPVC/EPDM blend was studied.The results showed that the optimal blending effect could be obtained by using onestep process at 170~175 ℃;HPVC/EPDM blend was a thermodynamically incompatible system and 9 phr of CPE or PVCgMAH was suitable interface compatibilizer for the HPVC/EPDM blend with ratio of 30/70;the interface strength of HPVC/EPDM blend could be characterized with Kraus equation.
