  • Patent number: 5183852
    Abstract: The invention pertains to blends of polymers containing a polyurethane, a polymer having reactive carboxyl moieties and a siloxane crosslinking agent. The polymer is most preferably represented by a terpolymer. The crosslinking agent contains reactive moieties such as hydroxy-, amine-, and epoxy-moieties and has a molecular weight which is preferably in the range of from about 1,500 to 60,000. The crosslinker can be used in relatively low molecular ratios vs. the polymerisable dicarboxylic acid in the polymer. Shaped articles made from the polyblends herein can be processed under high temperature conditions without suffering alterations; the articles so produced show desirable physical properties inclusive of reduced plasticiser migration, reduced fogging and enhanced low-temperature flexibility.

  • Patent number: 5137673
    Abstract: Plasticized polyvinyl butyral sheet optionally containing a gradient color band is formed by continuously extruding a sheet having a predetermined region across its width formed from melt issuing from a die at an increased mass flow rate in comparison with other portions of the melt forming the rest of the sheet and then forwardly distorting such sheet immediately after forming by preferentially stretching the side containing the predetermined region to form an arcuate shape of substantially uniform thickness. Arcuately shaped sections are then cut from the sheet to form discrete, shaped interlayer blanks having improved thickness uniformity and dimensional stability providing improved performance when used in laminated safety glass.

  • Patent number: 5130174
    Abstract: A shaped interlayer blank adapted for use with glass in a vehicle windshield, such blank formed of plasticized polyvinyl butyral and having a quadrilateral peripheral contour with two sides of arcuate shape and a wedge-shaped thickness profile. The blank preferably has an arcuate gradient color band substantially parallel to an arcuate edge of the blank in the greater thickness region of the blank. The wedge-shaped thickness gradually increases from about 30 mils to about 35 to 40 mils across the width of the blank. The blank is tailored for safety windshields featureing head-up displays where to function effectively the glass layes must be nonparallel and canted with respect to each other.
