Abstract:
The present invention is method for controlling the stereoisomerism of PVB resin as well as a PVB resin having a meso/racemic stereoisomer ratio of from about 2.5 to about 5.0. Manipulation of the PVB stereoisomer ratio can provide an additional method of controlling the physical properties of PVB, in addition to or in lieu of changing additives or manipulating the PVB composition.
