Abstract
A Pressure Sensitive Adhesive composition having low volatile organics content and low odor that is suitable for forming pressure sensitive adhesives containing an aqueous dispersion containing a blended mixture of: (a) a polymer obtained by the polymerization of (i) an internally plasticizing and cross-linkable long chain methyl ester having at least one double bond in said methyl ester chain; and (ii) one or more unsaturated monomers copolymerizable therewith; and (b) a surface-active agent.
Claims27
A pressure sensitive adhesive composition which comprises an aqueous dispersion comprising a blended mixture of:
- (a) a polymer obtained by the polymerization of
- (i) an internally plasticizing and cross-linkable long chain alkyl ester having one double bond located in said long chain alkyl ester;
- and
- (ii) one or more unsaturated monomers copolymerizable therewith wherein said one or more unsaturated monomers bond at the double bond location in said akyl ester;
- (b) a surface-active agent.
A process to make a pressure sensitive adhesive composition, which comprises mixing
- (a) a polymer obtained by the polymerization of
- (i) an internally plasticizing and cross-linkable long chain alkyl ester having one double bond located in said long chain alkyl ester;
- and
- (ii) one or more unsaturated monomers copolymerizable therewith wherein said one or more unsaturated monomers bond at the double bond location in said akyl ester;
- (b) a surface-active agent.
