Abstract

The production of EVA polymer based on polyethylene comprises mixing and extrusion of polyethylene 65-72, polyvinyl acetate 20-25 and EVA polymer 5-8 per cent by weight respectively. Also claimed is the product of the process. CLAIMED PRODUCT - The product has branched and interwoven polymer chains, with a basic skeleton of polyethylene. Acetate ramification blocks from the vinyl acetate are randomized in the product. EMBODIMENT - The production temperature is 120-180degreesC.
