Abstract

Structures comprises 5 sheets, viz.: 1 barrier layer of a copolymer of vinylidene chloride and at least one other olefinically unsatd. monomer, 2 glue layers of a block copolymer of styrene and butadiene, and 2 outer layers of rigid PVC or medium- or high-impact polystyrene having ASTM D-790 flexural modulus >150,000 psi. contg. a natural or synthetic rubber-type additive. The glue layer copolymer is opt. blended with a copolymer of ethylene and vinyl acetate, ethylacrylate or isobutyacrylate or with a chlorinated polyethylene.
