由于邻苯二甲酸酯可能具有毒性，因此使用对环境影响小的增塑剂是增塑剂添加剂行业最有趣的研究领域之一。在种类繁多的新型增塑剂中，重要的是要注意使用环己烷-1，2-二羧酸二（异壬基）酯（DINCH），其显示出与最常用的邻苯二甲酸酯（即邻苯二甲酸二异壬酯和邻苯二甲酸二（2-乙基己基）酯（DEHP））相似的结构。有必要评估与机械性能有关的加工条件（温度和固化时间），以研究替代传统增塑剂的可能性，并确定是否需要改变加工条件以用于工业应用。在这项工作中，我们进行了最佳固化条件和力学性能的DEHP和DINCH增塑剂的比较研究。所得结果表明，DINCH和DEHP基增塑溶胶的粘度相似。此外，从DINCH基增塑溶胶获得的柔性聚（氯乙烯）的机械性能是非常有趣的工业应用。所有这些都有利于用DINCH代替DEHP作为柔性聚氯乙烯的增塑剂。(c)2007 Wiley Periodicals，Inc.
The use of plasticizers with low environmental impact is one of the most interesting research fields in the plasticizer additives industry because of the possible toxicity of o-phthalates. Among the wide variety of new plasticizers, it is important to note the use of di(isononyl) cyclohexane-1,2-dicarboxylate (DINCH), which shows a structure similar to the mosi commonly used o-phthalates, that is, diisononyl phthalate and di(2-ethythexyl) phthalate (DEHP). It is necessary to evaluate the processing conditions (temperature and curing time) regarding the mechanical properties to study the possibilities for substituting conventional plasticizers and to determine whether changes in the processing conditions are needed for use in industrial applications. In this work, we carried out a comparative study of the optimum curing conditions and mechanical performance of DEHP and DINCH as plasticizers. The obtained results show that the viscosities of DINCH and DEHP-based plastisols were similar. Furthermore, the mechanical properties of the flexible poly(vinyl chloride) obtained from DINCH-based plastisols were very interesting for industrial applications. All of this favored the substitution of DEHP by DINCH as plasticizer for flexible poly(vinyl chloride). (c) 2007 Wiley Periodicals, Inc.
