摘要
烯类单体与聚酰胺(尼龙)纤维接枝共聚合已有报道.Varma等人研究了Ce4+引发丙烯腈、丙烯酰胺分别与尼龙纤维的接枝共聚反应。Lenka发表了用P2O48-引发甲基丙烯酸甲酯(MMA)与尼龙6纤维接枝共聚合的研究结果.Nayak等人报道了用乙酰丙酮锰为引发剂使MMA与尼龙6接枝共聚合.本文以二甲基苯胺(DMA)/硫酸铜为引发体系,用MMA接枝尼龙66纤维丝,研究了Cu2+浓度等因素对该接枝共聚反应的影响.
The ability of dimethylaniline(DMA)/CuSO4 initiator to induce grafting of methyl methacrylate(MMA) onto nylon 66 was investigated under different conditions. It was found that copolymerization reaction is greatly influenced by the temperature and time of the reaction, concentrations of MMA and DMA. The graft yield increases as the monomer concentration increases , there are optimal concentrations of DMA and Cu2+ ion, below or above these concentrations, lower grafting occurs. Raising the reaction temperature and increasing reaction time favorably influence grafting. The types of cupric salt also affect grafting to varying degrees. Addition of acetic acid enhances grafting, whereas formic acid decreases grafting.
