ABSTRACT:
Laminates of a polyvinyl butyral sheet with a sheet comprising a copolymer of a vinylaromatic monomer with an unsaturated dicarboxylic acid anhydride have high strength and can be made optically clear. The laminates can be in part foamed to provide insulation materials or metalplated to provide tough materials that could be used for example in automotive applications.
