  • Plasticized composition comprising polyvinylbutyral resin having controlled stereochemistry
    Patent number: 8329793
    Abstract: Provided herein is a polyvinylbutyral (PVB) resin having a meso/racemic stereoisomer ratio of from about 2.5 to about 5.0. Further provided herein is a plasticized PVB composition comprising the PVB resin. Manipulation of the PVB stereoisomer ratio can provide an additional method of controlling the physical properties of the PVB composition, in addition to or in lieu of changing additives or otherwise manipulating the PVB composition.
    Type: Grant
