摘要:
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.
摘要:
The present invention is a low-color plasticized PVB sheet and a process for preparing the same. The sheet of the present invention yields a YID measurement of less than 12. A sheet of the present invention is useful for making glass laminates that are useful in cars, boats, trains, buildings, and display cases, for example.

An acoustic solar control laminate comprising a multi-layer interlayer formed of a solar control film bonded between two polymeric sheets with at least one being an acoustic poly(vinyl acetal) sheet is provided.
摘要:
The present invention is an improved PVB composition comprising an adhesion control agent which is a mixture of potassium and magnesium salts in a ratio of from about 0.05:1 to about 5:1, by weight, potassium salts to magnesium salts. The present invention also describes a method for improved control of adhesion of PVB to glass.
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.
