    Abstract: Repulpable PSA compositions and constructions that exhibit high adhesive performance on a wide range of substrates are provided. In one embodiment, a PSA composition comprises a blend of two emulsion acrylic copolymers. The first type is a repulpable, emulsion acrylic copolymer that passes TAPPI UM 213. Preferably, the copolymer is prepared by sequential polymerization. The second type of copolymer is a non-repulpable, gpp or removable, repositionable, emulsion acrylic copolymer, also preferably prepared by sequential polymerization. The PSA compositions are inherently tacky and can be used in labels and tapes. In addition, they can be added to other PSAs as external tackifiers.

    Abstract: A pressure-sensitive adhesive composition comprises a mixture of (a) a non-crosslinking polymer and (b) a cross-linkable copolymer, said cross-linkable copolymer comprising the copolymer of the monomeric units of the polymer (a) and a cross-linkable comonomer. A cross-linkable comonomer is defined as one which when polymerized with one or more other monomers will result in the formation of a polymer containing a pendant reactive group which will self-cross-link. Preferably the composition of the cross-linkable copolymer is very similar to the composition of the non-cross-linking polymer. Cross-linkable monomers specified are N-methylol acrylamide, glycidyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate and the corresponding methacrylic acid derivatives. Exemplified monomers for the non-cross-linking resins are vinyl acetate, ethyl acrylate, butyl acrylate, octyl acrylate, vinylidene chloride and copolymers thereof. The composition may be dispersed as an aqueous emulsion, or dissolved in organic solvents and solvent mixtures. Further ingredients such as melamine formaldehde resins and acidic catalysts may be present.ALSO:A pressure-sensitive adhesive tape comprises a flexible backing, such as a polyethylene terephthalate film, coated with a composition comprising a mixture of (a) a non-crosslinking polymer, and (b) a crosslinkable copolymer, said crosslinkable copolymer comprising the copolymer of the monomeric units of the polymer (a) and a crosslinkable comonomer. A crosslinkable monomer is defined as one which when polymerized with one or more other monomers will result in the formation of a polymer containing a pendant reactive group which will self-crosslink. Crosslinkable monomers specified are N-methylol acrylamide, glycidyl acrylate. hydroxyethyl acrylate, hydroxypropyl acrylate and the corresponding methacrylic acid derivatives. In an example, (a) is a vinyl acetate:octyl acrylate copolymer (50:50), and (b) is a vinyl acetate:octyl acrylate:N-methylol acrylamide (50:50:4) copolymer. Other monomers specified for the non-cross-linking polymer are ethyl and butyl acrylate and vinylidene chloride. The compositions may also contain melamine formaldehyde resins and acidic catalysts to promote crosslinking. The compositions may be applied to the backing as solutions in organic solvents or as aqueous dispersions.
