Abstract
Abstract A laminate of a thermoplastic halocarbon polymer which comprises a laminate of a modified thermoplastic halocarbon polymer incorporating at least one functional group (a) selected from the group consisting of a carboxyl group, an acid anhydride group, a hydroxyl group and an epoxy group and a modified beta -olefin-series polymer incorporating at least one functional group (b) which is selected from the above-defined group but which differs from the functional group (a). The laminate of the present invention has high peeling strength and exhibits the advantages of the thermoplastic halocarbon polymer in combination with the inherent properties of the beta -olefin-series polymer with which it is laminated.
