  • POLY(VINYL ACETAL) RESIN COMPOSITIONS, LAYERS AND INTERLAYERS HAVING ENHANCED PROPERTIES
    Publication number: 20160159048
    Abstract: Resin compositions, layers, and interlayers comprising a poly(vinyl acetal) resin that includes residues of an aldehyde other than n-butyraldehyde are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties as compared to those formulated with comparable poly(vinyl n-butyral) resins.
    Type: Application

  • Continuous washing of poly(vinyl butyral)
    Patent number: 8304516
    Abstract: The present invention provides a method for continuously washing poly(vinyl butyral) in which a poly(vinyl butyral) slurry is passed through multiple continuous stirred tank reactors, each of which is adjusted to specific processing parameters that allow for continuous input, washing, and removal of poly(vinyl butyral). The resulting poly(vinyl butyral) can then be dried to form a powder resin that can be used in place of conventional poly(vinyl butyral) resin. In an alternative embodiment, a counter current screw washing unit is provided that passes wash water over the poly(vinyl butyral) in a direction opposite to the flow of the poly(vinyl butyral), thereby allowing the continuous washing of the poly(vinyl butyral) resin.
