Process for preparing polymer blends by recycling high-performance polymers

摘要

The invention relates to a process for preparing blends of high-performance polymers. The particular features are that at least two single-type polymers are treated with a solvent or a solvent mixture in which the polymers used are soluble, the polymers are thereby dissolved, and are then precipitated in a liquid medium, and recycled material is used for each of the polymeric constituents.
