Development of new environmentally friendly plasticizers

Abstract

A significant expansion of the range of polymer materials is associated with the constant improvement of technological processes for the production of polymer products, the quality of raw materials, the use of new additives to ensure the necessary consumer characteristics of products. Currently, due to the deterioration of the environmental situation associated with an increase in the amount of plastic waste, it is urgent to develop environmentally friendly additives that provide technical and operational characteristics for a certain period of operation, and then accelerate biodegradation in the environment. This paper considers the synthesis of a number of new environmentally friendly plasticizers based on adipic acid and aliphatic alcohols of normal and iso-structure C4-C10. The study of their physical and chemical characteristics showed the possibility of their practical use as PVC plasticizers. The tests carried out confirmed the good compatibility of the developed additives with polyvinyl chloride. The study of the glass transition temperature of the obtained samples of PVC compositions using the obtained plasticizers showed the high efficiency of their plasticizing action.
