Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di(2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed. Unlike other reported methods, this approach increases the interaction between phthalate and PVC to suppress its migration, not simply to enlarge its molecular size (or molecular weight). This methodology is highly versatile for producing the desired non-leaching PVC with a permanent plasticizer effect.
基于一种新型化合物，制备了不迁移的高增塑聚氯乙烯（PVC），该化合物可用作增塑剂，由邻苯二甲酸二（2-乙基己基）酯和氯化石蜡-52 衍生而来。所制备的 PVC 的增塑效率与 DOP 一样高，并且完全抑制了其迁移。与其他报道的方法不同，这种方法通过增加增塑剂与 PVC 之间的相互作用来抑制其迁移，而不是简单地增大其分子尺寸（或分子量）。这种方法对于生产具有永久增塑效果的理想不渗出 PVC 具有很高的通用性。
