Abstract
Polyvinyl chloride compositions are widely used to obtain various types of products. In the composition of the PVC composite, one of the main ingredients is a plasticizer, the introduction of which makes it possible to vary the characteristics of the obtained polymeric materials and products and significantly expand the range of their application. Manufacturability in the processing of polyvinyl chloride compositions serves as an important criterion for the suitability and economic efficiency of the developed plasticizer. In the modern world, the high quality of products is directly related to their environmental safety. In this regard, the work describes the production of environmentally friendly plasticizers based on adipic acid and ethoxylated butanol. Their physicochemical indicators have been investigated. The effect of the obtained additives on the rheology of PVC composites has been studied. The values of the flow characteristics of the melts of the developed PVC compositions plasticized with butyl butoxyethyl adipate and decyl butoxyethyl adipate were estimated. It was shown that the fluidity of melts, in comparison with compounds of a similar composition containing industrial dioctyl phthalate, is characterized by even slightly higher values.
Highlights
Polyvinyl chloride is widely used in many industries, such as medicine, transport, construction, packaging, and toys [1,2,3]
The corresponding alcohol and solvent were loaded into the chemical reactor, adipic acid was added in the ratio acid: alcohol = 1:1
The the synthesized synthesized derivatives derivatives of of adipic adipic acid acid butyl butyl butoxyethyl butoxyethyl adipate adipate and and decyl butoxyethyl adipate have a pronounced plasticizing effect with respect decyl butoxyethyl adipate have a pronounced plasticizing effect with respect to to PVC, PVC, which consists in a significant increase in the melt flow rate of PVC compounds
Summary
Polyvinyl chloride is widely used in many industries, such as medicine, transport, construction, packaging, and toys [1,2,3]. The polymer is exposed to chemical, biological, and physical factors, which leads to a significant irreversible change in its physical and chemical properties, that is, to aging [5,6,7]. In this regard, in the manufacture of materials and products from PVC, various chemical additives are used to ensure the required performance properties. The main role of auxiliary substances is to facilitate the processing of polymer mixtures and impart the necessary properties to finished products [8]. A wide range of physical properties of plastic compounds is obtained, which makes it possible to produce a wide variety of products: from very soft, gel-like to elastic, rigid materials [9]
