ABSTRACT:
The invention relates to new adhesive thermoplastic compositions.
The adhesive thermoplastic compositions according to the invention comprise at least one rubbery constituent and at least one resinous constituent and, if appropriate, other constituents, such as a plasticizer, filler and/or stabilizer, which are commonly incorporated into known adhesive thermoplastic compositions, generally called hot melts, but they also contain at least one special resin including regions of high cohesion incompatible with the rubbery constituent on the molecular scale, but miscible on the macroscopic scale.
The compositions according to the invention are particularly useful for sealing double glazing units.
