摘要 |
A pressure sensitive adhesive composition is described which is water-dispersible under acidic conditions. The composition comprises a terpolymer of a hydrophobic monomeric acrylic or methacrylic ester of a non-tertiary alcohol (monomer A); a polar monomer copolymerizable with said A monomer and having carboxylic, sulfonic acid or hydroxyl functionality or combinations thereof (monomer B); and a water soluble or water-dispersible macromolecular monomer of the formula X-Y-Z which is copolymerizable with A and B wherein X is a copolymerizable moiety containing a double bond, Y is a divalent linking group and Z is a water-dispersible polymeric moiety (monomer C). The combined acid groups employed in the B monomer are neutralized from 5 to 100% based on the total amount of acid groups in B. The composition further comprises tackifier and/or plasticizers at a level such that the ratio of terpolymer to additives falls within a range of from 0.2:1 to 5:1. The pressure sensitive adhesive composition is dispersible under a variety of pH conditions. Also described are tapes comprising the repulpable composition of the invention and their use in papermaking industry. |
