本工作旨在腰果酚类增塑剂的开发和性能优化。为此，通过不同的环氧化路线生产不同的增塑剂，其特征在于低毒理学和环境影响。增塑剂的特征在于烷基链双键的不同的环氧化产率。将腰果酚衍生的增塑剂的性质与邻苯二甲酸酯或天然衍生的商业增塑剂的性质进行比较。腰果酚衍生物增塑的软PVC的机械性能被证明是可比的，与商业增塑剂的PVC。腰果酚衍生物的增塑效率随着环氧化产率的提高而显著提高。此外，老化后进行的机械性能显示出腰果酚衍生的增塑剂的性能的优异稳定性，其特征在于较高的产率。老化后的性能保持指数的评价表明，与其它商业增塑剂相比，这种增塑剂显示出改进的性能稳定性。所获得的结果突出了双键到环氧树脂的高转化率的相关性，以生产高质量的增塑剂。(C)2016爱思唯尔有限公司版权所有。
This work is aimed to the development and property optimization of cardanol derived plasticizers. To this purpose, different plasticizers were produced though different epoxidation routes, characterized by low toxicological and environmental impact. The plasticizers are characterized by different yield of epoxidation of the alkyl chain double bonds. The properties of the cardanol derived plasticizers were compared to the properties of commercial plasticizers, either phthalates or natural derived. Mechanical properties of soft PVC plasticized by cardanol derivatives were shown to be comparable to,those of PVC with commercial plasticizers. The plasticizing efficiency of cardanol derivatives was significantly improved by increasing the yield of epoxidation. Also, mechanical properties performed after ageing showed the excellent stability of the properties of the cardanol derived plasticizer characterized by the higher yield. Evaluation of the property retention index after ageing indicated that such plasticizers showed an improved stability of properties compared to other commercial plasticizer. The results obtained highlight the relevance of an high conversion of the double bonds into epoxies in order to produce high quality plasticizers. (C) 2016 Elsevier Ltd. All rights reserved.
