Abstract

The aim of this paper is the determination of the migration and biodegradation of the PVC additives in the soil. Epoxidized Sunflower Oil (ESO) was used as a thermal organic co-stabilizer for PVC; it was obtained by epoxidation of commercial sunflower oil. Two plasticizers were used: dioctyl phthalate (DOP) and diisononyl adipate (DINA). A natural aging test on site in a garden soil (Tizi Ouzou, Algeria) of the PVC samples was investigated for 6 months. The samples were characterized by Fourier transform infrared (FTIR).The morphological changes were followed by scanning electron microscopy (SEM). The evolution of the bacterial growth, identification using biochemical tests, variation of pH and variation of mass were investigated. The results showed that the nature of the plasticizer and heat stabilizer affects the properties of PVC as well as the phenomena of migration and biodegradation.

增塑聚氯乙烯新配方的影响研究

本文的目的是测定PVC添加剂在土壤中的迁移和生物降解。采用环氧葵花油（ESO）作为PVC的热有机共稳定剂；它是通过商业葵花油的环氧化得到的。使用了两种增塑剂：邻苯二甲酸二辛酯（DOP）和己二酸二异壬酯（DINA）。在花园土壤（阿尔及利亚Tizi Ouzou）中对PVC样品进行了为期6个月的现场自然老化试验。用傅立叶变换红外光谱（FTIR）对样品进行了表征，用扫描电子显微镜（SEM）观察了样品的形貌变化。研究了细菌生长的演变、生化鉴定、pH值的变化和质量的变化。结果表明，增塑剂和热稳定剂的性质影响PVC的性能以及迁移和生物降解现象。

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
