Abstract

Polymeric packaging materials are one of the factors of environmental pollution. Reducing the environmental burden is possible by increasing the environmental friendliness of packaging materials. In this work, we study polymer films based on polyvinyl chloride (PVC) with a copolymer of 3-hydroxybutyrate with 3-hydroxyhexanoate P (3-GB) (3-GG) with different component ratios. The process of processing blends in the process of obtaining a packaging film is considered. The optical characteristics of the obtained films are determined. Thermal analysis of the obtained films was carried out using the differential scanning calorimetry (DSC), TGA, and thermomechanical analysis (TMA) methods. The degree of gelling of the resulting mixture was determined. It is shown that PHB has miscibility with PVC.

摘要

聚合物包装材料是环境污染的因素之一。通过提高包装材料的环境友好性来减轻环境负担是可行的。在这项工作中，我们研究了基于聚氯乙烯（PVC）与3-羟基丁酸与3-羟基己酸的共聚物P（3-GB）（3-GG）且具有不同组分比例的聚合物薄膜。考虑了在获得包装薄膜过程中共混物的加工过程。测定了所得薄膜的光学特性。使用差示扫描量热法（DSC）、热重分析（TGA）和热机械分析（TMA）方法对所得薄膜进行了热分析。测定了所得混合物的凝胶化程度。结果表明，聚羟基丁酸酯（PHB）与PVC具有混溶性。
