摘要： A transparent polymeric laminate of plasticized polyvinyl butyral sheet chemically linked by urethane groups to a thermoset polyurethane layer formed as the reaction product of a cross-linkable mixture containing diisocyanate and polyether polyol containing primary or secondary hydroxyl groups and having a molecular weight between about 250 to about 8000.

摘要： A method of forming a bilayer glazing panel by providing an optically clear prelaminate of stretched polyester film coated with a cross-linked, self-healing polyurethane layer; assembling the prelaminate with a layer of plasticized partial polyvinyl butyral with the side of the polyester film without the polyurethane layer in facing contact with a subjacent textured surface of the partial polyvinyl butyral layer; clamping the assembled layers in a perimeter anchoring system; sequentially carrying out the following steps i), ii), iii), and optionally the above clamping step within an air autoclave; i) deairing the interface between the polyester film and plasticized partial polyvinyl butyral; ii) forcing localized regions of the layers within the perimeter anchoring system against a sheet of glass; and iii) subjecting the assembly of step ii) to elevated temperature and pressure while the plastic layers remain clamped within the perimeter anchoring system to firmly bond the plastic layers and glass sheet together.
