细叙百年峥嵘岁月20世纪20年代,邻苯二甲酸酯类塑化剂轻巧地插入到塑料聚合物分子链之间,削弱其间应力,降低结晶度,增加分子链的移动性,从而使聚合物的柔韧性增加,以高性价终结了气味很大且易挥发的樟脑塑化剂时代。1935年聚氯乙烯生产工业化,邻苯二甲酸酯类作为增塑剂得到了更广泛的应 In the 1920s, phthalate plasticizers were inserted lightly between plastic polymer chains to weaken the stress, reduce the degree of crystallinity and increase the mobility of molecular chains, so that polymerization The flexibility of the material increases, ending the era of camphor plasticizers with high odor and volatility at a high price. 1935 PVC industrialized, phthalates as plasticizers have been more widely used
