A method for the production of semifinished products of high - or ultra-high-molecular-weight polymers, semi-finished products produced in such a way as well as their use

摘要

A method for the production of semifinished products, the form of - and / or finished articles made of highly - and ultrahigh polymers by a sintering process at temperatures between 150 and 300°C. and pressures between 50 and 400 bar, characterized in that the in a container containing an oxygen-free atmosphere enclosed polymer to the semi-finished product and / or molded part, and subsequently separated from the container and the container is embedded in an additional polymer, as a result of which a homogenization of the pressure conditions of the package surface area is achieved.
