    摘要: A polyvinyl butyral (PVB) resin has a meso/racemic stereoisomer ratio of from about 2.5 to about 5.0. A process for preparing this PVB resin is described. Manipulation of the PVB stereoisomer ratio can provide an additional method of controlling the physical properties of a plasticized composition comprising the PVB resin, in addition to or in lieu of changing additives or otherwise manipulating the components of the plasticized PVB resin composition.

    摘要: The present invention describes laminate articles comprising a stiff, low-color PVB sheet having a YID of less than 12 and having a low concentration of plasticizer in the PVB composition, wherein the sheet is prepared from a composition that includes a PVB bleaching compound. A sheet of the present invention is useful for making glass laminates useful for parts in making cars, boats, trains, buildings, display cases, and other articles that utilize transparent glass laminates.
