  • Removable pressure-sensitive adhesive compositions comprising acrylic based emulsion polymers
    Patent number: 5240989
    Abstract: A removable pressure sensitive adhesive composition comprises an acrylic-based emulsion polymer having a gel content of from about 70 to about 90%. The polymer comprises about 90 to 99.5 parts alkyl acrylate monomers, up to about 2 parts polar monomers and up to about one part of a multifunctional acrylate monomer. The polymer is sythesized in the presence of a combination of anionic and non-ionic emulsifiers wherein the amount of anionic emulsifer exceeds the amount of non-ionic emulsifier. The composition preferably comprises one or more adhesion stabilizers, preferably a plasticiser in an amount of up to about 3% by weight and a protective colloid in an amount of up to about 1% by weight.
