  • Caustic removable hot melt adhesive formulations
    Patent number: 8461277
    Abstract: An additive composition for imparting caustic removability to a hot melt adhesive comprises a low molecular weight ?,? ethylenically unsaturated anhydride-containing or acid-containing polymer. The polymer is selected from the group consisting of a low molecular weight carboxylic anhydride homo-polymer or the at least partial ester thereof, a low molecular weight carboxylic anhydride copolymer or the at least partial ester thereof, a low molecular weight carboxylic anhydride polyolefin, a low molecular weight carboxylic anhydride vinyl aromatic copolymer, and a low molecular weight carboxylic anhydride grafted copolymer, or the combination or mixtures thereof. A caustic removable hot melt adhesive composition comprises a hot melt adhesive additive and a conventional hot melt adhesive resin. A caustic removable adhesive label comprises a substrate and a caustic removable hot melt adhesive composition which includes an additive composition.
