<p>PROBLEM TO BE SOLVED: To provide a high-frequency-weldable resin which sufficiently generates heat under a high frequency and, when formed into a layer on the surfaces of substrates, enables various members or materials to be bonded to each other by a high frequency and to provide a method for producing a high-frequency- weldable film which is prepared by using the resin and is well bondable by a high frequency to polyolefin substrates. SOLUTION: This high-frequency-weldable resin is a copolymer prepared by copolymerizing (a) a polymerizable monomer having a tertiary carbon structure and a double bond, (b) at least one other radical-polymerizable monomer, and preferably (d) an olefin homopolymer or copolymer having molecular terminals modified with radical-polymerizable double bonds. The method for producing a high-frequency-weldable film comprises coextruding the above high-frequency-weldable resin together with an olefin resin into an integral film laminate.</p> |
