A process is disclosed for recovering soft poly(vinyl butyral) from a plasticized poly(vinyl butyral) multilayer sheet comprising stiff poly(vinyl butyral) and soft poly(vinyl butyral). The multilayer sheet. which may be scrap or recycled material. is first converted to a granulate form and then treated with plasticizer. This plasticizer treatment serves to remove the soft poly(vinyl butyral) component from the granulate. but thereby provides a varnish comprising the soft poly(vinyl butyral) mixed with excess plasticizer. This varnish is however highly viscous and thus difficult to handle or mechanically process. The present disclosure provides a solution to this handling problem by the addition of soft poly(vinyl butyral) having a lower concentration of plasticizer to the varnish. until a product is obtained having a sufficiently low concentration of plasticizer to render the product capable of mechanical processing. for example pelletizing. The resulting product can then be utilized to form soft poly(vinyl butyral) sheets, thereby improving the recyclability of scrap multilayer poly(vinyl butyral) materials.
