ABSTRACT:
The invention relates to adhesive compositions comprising zwitterionic copolymers, including repulpable adhesive compositions, and adhesive tapes made with such compositions. The adhesive compositions comprise a zwitterionic copolymer and a zwitterionic plasticizer or tackifier which can be coated on a backing to form an adhesive tape. The repulpable tapes are formed from a repulpable adhesive composition comprising a zwitterionic copolymer coated on a repulpable backing. Examples of zwitterionic copolymers are those derived from the monomers N-(3-sulphopropyl)-N-methacryloxy-ethyl-N,N-dimethyl ammonium betaine or N-(3-sulphopropyl)-N-acryloxy-ethyl-N, N-dimethyl ammonium betaine. Some of the zwitterionic copolymers are novel.
