ADDITIVE FOR CAUSTIC REMOVABLE HOT MELT ADHESIVES AND FORMULATIONS CONTAINING THE SAME |
摘要 |
An additive composition for imparting caustic removability to a hot melt adhesive includes an ester functionalized polymer having a polymeric backbone and, pendent thereon, one or more dicarboxylic acid moieties in at least partial ester form. The polymeric backbone has a weight average molecular weight less than 50,000. The ester functionalized polymer may be, for example, an at least partial ester of a maleated hydrocarbon. The additive may further include a low molecular weight α,&bgr; ethylenically unsaturated anhydride-containing or acid-containing polymer. 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. The caustic removable hot melt adhesives can be used on labels for articles, such as glass bottles. |
