Abstract
Abstract A laminate of a thermoplastic halocarbon polymer which comprises a laminate of (i) a layer of a modified thermoplastic ialocarbon (chloro- or fluorocarbon) polymer incorporating at east one functional group (a) which is a carboxyl, acid anhydride, hydroxyl or epoxy group, e.g. a modified vinylidene fluoride, and (ii) a layer of a modified a-olefin-series polymer ncorporating a different one of the groups (a), e.g. a modified polyethylene. Both polymers may be mixed with other polymers e.g. (i) a methyl methacrylate and (ii) a polyamide or polyester. The amount of each functional group is 0.001-0.3 mol/100 g. The aminates can include other layers. The layers may be adhered by heat or adhesive. The laminates have high peeling strength and exhibit the advantages of both the polymers.
