Method for Mechanical and Thermal Destruction Thermoplastic Polymers for Reproduction

摘要

This invention applies to the processing of thermoplastic polymers, specifically - to multiply recycling of thermoplastic polymers. The aim is to prevent or practically eliminate mechanical and thermal destruction of conventional thermoplastic polymers by recycling using a well-known principle, that is fractionation of two incompatible polymers in tubes or different closed-type canals. When this takes place, migration of the solution with the smaller viscosity in the direction of the tube wall forms a film. For recycling of polymers, it is proposed to use liquid crystal thermotropic polymer (LCP) as an additive with 3 times lower viscosity than the recycling polymer. The LCP will be added before or at process time. The volume of LCP addition will be calculated so that it will make a 50 mkm film on the surface of the extrudate.
