Abstract
Abstract What are disclosed are plastisols comprising a finely divided vinyl chloride polymer and the usual fillers, additives, and plasticizers, to which plastisols is added, as an adhesion promoter, the condensation product formed between (1) a polyaminoamide, comprising polymerized fatty acids and an excess of a polyalkylene polyamine and (2) a carboxylic acid or an ester thereof, and methods for coating or adhering a substrate with such plastisols by applying said plastisols to the substrate and baking at temperatures of 90° C. and up.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A platisol comprising a polymer of vinyl chloride, a plasticizer therefor, a filler, and from 0.5 to 5 pervent, by weight of said plastisol, of an adhesion promoter which is the condensation production formed between (A) a polyaminoamide which is, in turn, the reaction product of a polymerized fatty acid and an excess, based on carboxyl groups, of a polyalkylene polyamine, and (B) from 3 to 20 percent, by weight of the fatty acid present in said polyaminoamide, of a carboxylic acid or ester of the formula R.sup.1 --(COOR.sup.2).sub.n, wherein R 1 is an optionally substituted saturated or unsaturated aliphatic, araliphatic, or aromatic hydrocarbon having 2 to 18 carbon atoms, R 2 is hydrogen or alkyl having from 1 to 8 carbon atoms, and n is 1 or 2.
Claim 2
Dependent Claim
129 words
A platisol comprising a polymer of vinyl chloride, a plasticizer therefor, a filler, and from 0.5 to 5 pervent, by weight of said plastisol, of an adhesion promoter which is the condensation production formed between (A) a polyaminoamide which is, in turn, the reaction product of a polymerized fatty acid and an excess, based on carboxyl groups, of a polyalkylene polyamine, and (B) from 3 to 20 percent, by weight of the fatty acid present in said polyaminoamide, of a carboxylic acid or ester of the formula R.sup.1 --(COOR.sup.2).sub.n, wherein R 1 is an optionally substituted saturated or unsaturated aliphatic, araliphatic, or aromatic hydrocarbon having 2 to 18 carbon atoms, R 2 is hydrogen or alkyl having from 1 to 8 carbon atoms, and n is 1 or 2.
Claim 3
Dependent Claim
90 words
A plastisol as in claim 1 wherein said polyaminoamide (A) is formed between an amount of a polymerized mixture of fatty acids with a high proportion, X, of trimeric and higher polymeric fatty acids, and an amount of an excess of a polyalkylene polyamine having an imidazoline content, Y, wherein, if the value of either X or Y is less than 40 percent, then the value of the other component is at least (40+Z) percent, where Z is the difference between the smaller value of X and Y and 40.
Claim 4
Dependent Claim
47 words
A plastisol as in claim 2 wherein, if the value of either X or Y is less than 40 percent, then the value of the other component is at least (40+2Z) percent, where Z is the difference between the smaller value of X and Y and 40.
Claim 5
Dependent Claim
25 words
A plastisol as in claim 1 wherein said carboxylic acid or ester (B) is an aromatic carboxylic acid or an ester of such an acid.
Claim 6
Dependent Claim
34 words
The method of coating or adhering a substrate which comprises applying a plastisol as in claim 1 to said substrate and baking said plastisol and substrate at a temperature of at least 90° C.
Claim 7
Dependent Claim
34 words
The method of coating or adhering a substrate which comprises applying a plastisol as in claim 2 to said substrate and baking said plastisol and substrate at a temperature of at least 90° C.
Claim 8
Dependent Claim
34 words
The method of coating or adhering a substrate which comprises applying a plastisol as in claim 3 to said substrate and baking said plastisol and substrate at a temperature of at least 90° C.
Claim 9
Dependent Claim
34 words
The method of coating or adhering a substrate which comprises applying a plastisol as in claim 1 to said substrate and baking said plastisol and substrate at a temperature of at least 90° C.
Claim 10
Dependent Claim
34 words
The method of coating or adhering a substrate which comprises applying a plastisol as in claim 4 to said substrate and baking said plastisol and substrate at a temperature of at least 90° C.
