Claims
- 1. An adhesive composition comprising:
- (a) an acrylate or methacrylate ester monomer;
- (b) a polymerization catalyst;
- (c) a mixture of
- (A) one or more of the members of the group consisting of:
- (1) chlorinated polyethylene polymer resin and sulfonyl chloride;
- (2) chlorosulfonated polyethylene polymer resin; and
- (3) a polymer-in-monomer solution and (B) a graft co-polymer resin having a backbone polymer with a glass transition temperature substantially below ambient temperature and a grafted polymer resin having a glass transition temperature substantially above ambient temperature; and
- (d) an effective amount of strong organic acid wherein the acid has a dissociation constant (K.sub.d or K.sub.1 d) within the range of from about 1.times.10.sup.-2 to about 10.times.10.sup.-1 or wherein an 0.2 N aqueous solution of the acid has a pH in the range of from about 1.2 to 2.0 at 2.5.degree. C.
- 2. The adhesive composition of claim 1 wherein the strong organic acid has a dissociation constant (K.sub.d or K.sub.1d) within the range of from about 1.times.10.sup.-2 to about 1.times.10.sup.-1.
- 3. The adhesive composition of claim 1 wherein the strong organic acid has a dissociation constant (K.sub.1 or K.sub.1d) or about 1.4.times.10.sup.-2.
- 4. The adhesive composition of claim 3 wherein the strong organic acid is maleic acid.
- 5. The adhesive composition of claim 1 wherein the strong organic acid is added to the adhesive formulation as a dispersion in an amount ranging from about 0.1 parts to 20 part per hundred.
- 6. The adhesive composition of claim 1 wherein the strong organic acid is added to the adhesive formulation as a dispersion in an amount ranging from about 0.5 to about 10 parts per hundred.
- 7. The adhesive composition of claim 1 wherein the strong organic acid is added to the adhesive formulation as an aqueous solution in an amount ranging from about 0.1 parts to 20 parts per hundred.
- 8. The adhesive composition of claim 1 wherein the strong organic acid is added to the adhesive formulation as an aqueous solution in an amount ranging from about 0.5 parts to 10 parts per hundred.
- 9. The adhesive composition of claim 1 wherein an 0.2 N aqueous solution of the strong organic acid has a pH in the range of from about 1.3 to 2.0.
