摘要 采用Haake转矩流变仪研究了甲基丙烯酸缩水甘油酯(GMA)-苯乙烯(St)多组分单体熔融接枝高全同聚1-丁烯(iPB)。考察了温度,过氧化二异丙苯(DCP),GMA,St用量对接枝的影响。结果表明:在180℃下,DCP用量为0.8 phr时,接枝率最高;DCP用量一定时,随着GMA用量增加,接枝率增加,熔体流动速率减小;St作为共单体可明显提高GMA的接枝率。 The authors studied high isotactic poly(1-butene) (iPB) melt grafted by multi-monomers glycidyl methacrylate (GMA)/styrene (St) by means of Haake torque rheometer. The effects of temperature, dicumyl peroxide (DCP) amount and monomers concentration on grafting reaction were examined. The resuhs show that the grafting ratio reaches its maximum when the DCP amount is 0.8 phr at 180 ℃. The grafting ratio increases while the melt flow rate of the grafted iPB decreases with the augmentation of GMA concentration in the case of setting DCP amount at a given value; St as a co-monomer can significantly enhances the grafting ratio of GMA.
