Abstract: Provided are a reprocessed material of recycled polyvinyl butyral and the method for producing the same. The method comprises steps (A) and (B); step (A): heating a first mixture comprising recycled polyvinyl butyral and an antiblocking agent; and step (B): adding a free radical initiator into the first mixture to undergo a reaction to obtain the reprocessed material of recycled polyvinyl butyral; wherein the free radical initiator comprises an azo compound, an organic peroxide or a combination thereof; the reprocessed material of recycled polyvinyl butyral has a MI of greater than 7 g/10 min at 190° C. and under 2.16 kg of load. The reprocessed material of recycled polyvinyl butyral has excellent reprocessability, so it is applicable to make a hot adhesive and a composite material film.

Abstract: A foam composition comprises a recycled polyvinyl butyral in an amount from 5 wt % to 70 wt %; an ethylene-ester copolymer in an amount from 10 wt % to 70 wt %; a foaming agent in an amount from 0.5 wt % to 3.5 wt %; a peroxide crosslinking agent in an amount from 0.5 wt % to 3.0 wt %; and a hydrazide crosslinking agent in an amount from 0.1 wt % to 2.5 wt %, based on a total weight of the foam composition. A foam produced from the foam composition can avoid emitting an unpleasant odor of aldehydes, and the foam also has good mechanical properties and good resilience.
