A process for the continuous production of polyethylene material with an increased starch and a high modulus of elasticity.

摘要

A method for the continuous preparation of apolyethylene having high strength and high modulus ofelasticity is here disclosed which comprises the steps ofmixing 100 parts by weight of an ultra-high-molecular-weight polyethylene powder having an intrinsic viscosityof 5 to 50 dl/g in decalin at 135°C with 2 to 50 parts byweight of a liquid organic compound having a boiling pointhigher than the melting point of the polyethylene, feedingthe resulting mixture to between a pair of upper and lowerendless belts facing each other, continuously compression-molding the mixture at a temperature less than the meltingpoint of the mixture by pressing means disposed inside theendless belts, and rolling and then drawing the same.
