Abstract

The graft block copolymer (GBC), based on the functionalized ethylene-vinyl acetate copolymer and monoisocyanateurethane of reactive olygomers of soybean oil, was synthesized. The structure of the copolymer was confirmed by IR-spectroscopy and gel permeation chromatography. Physico-chemical characteristics of the GBC were studied by thermal gravimetric analysis and differential scanning calorimetry. It was found that the obtained GBC has high heat resistance, the glass transition temperature of the copolymer is shifted towards lower temperatures. Efficient use of GBC as compatibilizer for composite materials based on recycled polypropylene and crumb rubber was shown. [ABSTRACT FROM AUTHOR]
