Abstract
Abstract The caulking or sealing composition of the invention has as its binder an acrylic backbone containing pendant unsaturated groups, preferably derived from drying oil fatty acids, and attached to the acrylic backbone through amidoester linkages. The acrylic modified product has the flexibility and durability characteristic of acrylics, and the advantage that the composition will cure similarly to drying oils, using driers such as cobalt naphthenate and zinc naphthenate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
61 words
The composition of claim 1 in which R5 is H, R1 is H or a lower alkyl radical, R3 is methyl, R4 has about 18 carbon atoms or less, the amount of said unsaturated carboxylic acid is from 1 to 5 weight percent of the backbone monomers, no more than about 5 percent by weight of the units having the formula:
Claim 2
Dependent Claim
49 words
The composition of claim 2 in which R1 is H or methyl, R2 has 2 to 3 linear carbon atoms between the nitrogen and oxygen atoms, said ratio is 1:0.6 to 1:0.4, and the Tg of the backbone polymer free of pendant ester groups is below about 0* C.
Claim 3
Dependent Claim
13 words
The composition of claim 3 in which said Tg is below -10* C.
Claim 4
Dependent Claim
58 words
The composition of claim 1 in which an organic solvent is present, and the polymer is predominantly an ester of acrylic acid and an alkanol having one to four carbon atoms, with, in smaller amounts, an ester of methacrylic acid and an alkanol having one to four carbon atoms, methacrylonitrile or acrylonitrile, and methacrylic acid or acrylic acid.
Claim 5
Dependent Claim
60 words
The composition of claim 2 in which an organic solvent is present, and the polymer is predominantly an ester of acrylic acid and an alkanol having one to four carbon atoms, with an ester of methacrylic acid and an alkanol having one to four carbon atoms, methacrylonitrile or acrylonitrile, and methacrylic acid or acrylic acid being present in smaller amounts.
Claim 6
Dependent Claim
21 words
The composition of claim 4 in which said fatty acids are predominantly at least one of oleic, linoleic, or linolenic acid.
Claim 7
Dependent Claim
27 words
The composition of claim 6 containing a silane selected from the group consisting of vinyltriethoxysilane, gamma -methacryloxypropyl-trimethoxysilane, gamma -mercaptopropyltrimethoxysilane, gamma -glycidoxy-propyltrimethoxysilane, Beta -(3,4-epoxycyclohexy)ethyltrimethoxy-silane, gamma -aminopropyltriethoxysilane, and N-(dimethoxymethyl-silylisobutyl)ethylenediamine.
Claim 8
Dependent Claim
