MODIFICATION OF VIRGIN AND/OR RECYCLED CONSTRUCTION POLYMERS, USING POLY VINYL BUTYRAL (PVB), OR RECYCLED PVB FROM INDUSTRIAL WASTE STREAMS AND AN ALLOYING COPOLYMER

摘要

Plasticizer composition for a construction polymers. Said plasticizer composition comprises 35-65% (by weight) of polyvinylbutyral (PVB) and 65-35% (by weight) of one or more alloying copolymers. The construction polymer is e.g. polyvinyl chloride (PVC), polypropylene (PP), poly urethane (PU), acryl butadiene styrene (ABS) or polyethylene (PE) and/or mixtures thereof. The resulting polymer construction polymer constitutes 25-90% by weight and the plasticizer composition constitutes 10-75% by weight of the polymer blend composition. The components of the plasticizer composition are non-migrating and provide surprising physical properties of the final polymer composition.
