Abstract
(EN)
The present invention relates to a branched polyethylene-containing masterbatch composite and a processing method for same, which comprises in terms of 100 parts by weight: highly branched polyethylene 70-99 parts and carbon nanotubes or graphene 1-30 parts. The degree of branching of the highly branched polyethylene is 70-130 branch chains/1000 carbons, the weight-averaged molecular weight is 66 thousand to 436 thousand, and the Mooney viscosity is 6-93 ML(1+4) 125°C. The beneficial effects are such that the highly branched polyethylene is an ethylene homopolymer, is a high-performance polyolefin product, provides rubber elasticity in room temperature, and is characterized by a small density, large curvature, high impact resistance in a low temperature, and being easy to process.
