ABSTRACT:
Polysiloxane-polycarbonate block copolymers provide ductile, structural adhesive layers for bonding laminates. They are particularly useful as an adhesive and structural element in preparing polycarbonate containing composites which retain their integrity. Laminates of glass, polycarbonate, other resins separately and in various combinations and the adhesive layer provide glazing and structural units of relatively light weight and thickness which have good energy absorption, clarity, strength and integrity and are penetration resistant over a wide range of temperatures.
