The effect of ethoxylated alcohol adipates on the rheology of PVC compound melts

Abstract

Polyvinyl chloride compositions are widely used to produce various types of products. In the PVC composition one of the main ingredients is a plasticizer, which makes it possible to vary the characteristics of the polymer materials and products obtained, as well as significantly expand the scope of their application. Processability in treatment of the vinyl chloride compositions is an important criterion for both the suitability and cost-effectiveness of a developed plasticizer. In the modern world, high product quality is directly related to its environmental safety. In recognition of it, environmentally friendly plasticizers, based on adipic acid and oxyethylated butanol, have been developed. The effect of the obtained additives on the rheology of PVC compositions has been investigated. The values of fluidity characteristics of melts of the developed PVC compositions plasticized with butylbutoxyethyladipinate and decylbutoxyethyladipinate have been estimated. It has been shown that the fluidity of melts containing the developed additives is characterized by higher values of the melt flow index in comparison with similar compositions containing industrial dioctyl phthalate.
