Graft block copolymer based on functionalized ethylene-vinyl acetate copolymer and liquid rubber. Synthesis, structure and properties.

Graft block copolymer (GBC) based on functionalized ethylene-vinyl acetate copolymer and macrodiisocyanate based on liquid rubber was synthesized, the structure of GBC was confirmed by IR-spectroscopy. Physico-chemical characteristics of the GBC were investigated by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). It was found that the GBC has a higher thermal stability compared with the original components, and the glass transition temperature is shifted to lower temperatures. Efficient use of PBS as compatibilizer for composite materials based on recycled polypropylene and crumb rubber was shown. [ABSTRACT FROM AUTHOR]
