Abstract
Crosslinkable copolymers suitable for use as elevated temperature pressure-sensitive adhesives comprise randomly arranged silarylene units and siloxane units. Preferably, there is present in the copolymer backbone in the range of 0.8 to 1.2 siloxane to silarylene units, and there being present in the copolymer a crosslinking functionality.
