Abstract
Abstract Primer compositions useful in the cure of adhesive compositions containing acrylate and/or methacrylate monomers, chlorosulfonated polyethylene and a peroxy free radical generator comprise (a) the condensation product of an aldehyde and a primary or secondary amine and (b) a salt of a non-transition metal selected from the group consisting of lead, tin, zinc, calcium, strontium, barium and cadmium. These primers and the two part adhesives prepared therewith are characterized by superior speed of cure and final bond strength.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
68 words
A primer for peroxy initiated chlorosulfonated polyethylene/acrylate or methacrylate adhesives comprising (a) the condensation product of an aldehyde and a primary or secondary amine and (b) a salt of a non-transition metal selected from the group consisting of lead, tin, zinc, calcium, strontium, barium and cadmium wherein the ratio of the aldehyde-amine condensation product to the salt of a non-transition metal is from about 1:1 to about 15:1.
Claim 2
Dependent Claim
68 words
A primer for peroxy initiated chlorosulfonated polyethylene/acrylate or methacrylate adhesives comprising (a) the condensation product of an aldehyde and a primary or secondary amine and (b) a salt of a non-transition metal selected from the group consisting of lead, tin, zinc, calcium, strontium, barium and cadmium wherein the ratio of the aldehyde-amine condensation product to the salt of a non-transition metal is from about 1:1 to about 15:1.
Claim 3
Dependent Claim
18 words
The primer of claim 1 wherein the aldehyde-amine condensation product is a butyraldehyde-aniline or butyraldehyde-butyl amine condensation product.
Claim 4
Dependent Claim
32 words
The primer of claim 1 wherein the metal salt is selected from the group consisting of calcium naphthenate, strontium naphthenate, barium naphthenate, zinc naphthenate, cadmium iodide, dibutyl tin dilaurate and lead naphthenate.
Claim 5
Dependent Claim
37 words
The primer of claim 1 wherein the aldehyde amine condensation product is used in amounts of up to 15% and the non-transition metal salt in an amount of up to 5% by weight of the adhesive composition.
Claim 6
Dependent Claim
37 words
The primer of claim 1 wherein the aldehyde-amine condensation product is used in an amount of 0.15 to 5% and the non-transition metal salt in an amount of 0.00001% to 0.5% by weight of the adhesive composition.
Claim 7
Dependent Claim
104 words
A two-part adhesive which comprises a joined mixture of (1) an acrylate or methacrylate monomer, a chlorosulfonated polyethylene and a peroxy polymerization initiator and (2) an aldehyde-amine condensation product and a salt of a non-transition metal selected from the group consisting of lead, tin, zinc, calcium, barium, strontium and cadmium wherein the aldehyde-amine condensation product is used in an amount of 0.15 to 5% and the non-transition metal salt in an amount of 0.00001 to 0.5% by weight of the adhesive composition and wherein the ratio of the aldehyde-amine condensation product to the non-transition metal salt is within the range of 1:1 to 15:1.
Claim 8
Dependent Claim
104 words
A two-part adhesive which comprises a joined mixture of (1) an acrylate or methacrylate monomer, a chlorosulfonated polyethylene and a peroxy polymerization initiator and (2) an aldehyde-amine condensation product and a salt of a non-transition metal selected from the group consisting of lead, tin, zinc, calcium, barium, strontium and cadmium wherein the aldehyde-amine condensation product is used in an amount of 0.15 to 5% and the non-transition metal salt in an amount of 0.00001 to 0.5% by weight of the adhesive composition and wherein the ratio of the aldehyde-amine condensation product to the non-transition metal salt is within the range of 1:1 to 15:1.
Claim 9
Dependent Claim
21 words

Claim 11
Dependent Claim
40 words
The two part adhesive of claim 6 wherein the aldehyde-amine condensation product of (2) is used in amounts of up to 15% and the non-transition metal salt in an amount of up to 5% by weight of the adhesive composition.
