Production of alloys based on polyvinyl chloride and a plastic material comprises coprecipitating alloy particles from solution by injecting a nonsolvent

摘要

Production of alloys based on polyvinyl chloride (PVC) and a plastic material comprises dissolving the PVC and plastic material in a solvent, coprecipitating the PVC and plastic material in the form of alloy particles by injecting a nonsolvent into the solution, and recovering the alloy particles. An independent claim is also included for an alloy produced as above in the form of spherical particles with a mean diameter of 100-800 Microm.
