  • Patent number: 4059715
    Abstract: A method for forming a strong bond between a substrate and a solid thermoplastic polymer which comprises melting a thermoplastic polymer having an effective open time (a period after melting the polymer during which it remains aggressively tacky and bondable below the melting temperature), cooling it below the melting temperature, contacting the open polymer with a substrate and allowing the polymer to revert to its non-bondable, solid state. Also disclosed are a class of copolyesters suitable for use in the method and certain novel articles adapted for carrying out the method.
