Abstract
Abstract An improved composition is disclosed which consists of organic resins and silanes. The compositions are useful finishing resins for textiles, fibers and paper. An example of the improved composition is a copolymer resin containing at least one type of acrylic acid ester combined with at least one type of unsaturated aliphatic acid and, a silane containing epoxy groups.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
77 words
An improved resin for resin finishing textiles, fibers and paper which is a composition of matter which consists essentially of (A) copolymeric organic resins which are prepared from unsaturated aliphatic organic acids and an ester selected from the group consisting of (i) acrylic acid esters and (ii) methacrylic acid esters, the improvement comprising the addition of (B) 0.1-10 weight percent, based on the weight of the components (A) and (B), of a silane which contains epoxy groups.
Claim 2
Dependent Claim
77 words
An improved resin for resin finishing textiles, fibers and paper which is a composition of matter which consists essentially of (A) copolymeric organic resins which are prepared from unsaturated aliphatic organic acids and an ester selected from the group consisting of (i) acrylic acid esters and (ii) methacrylic acid esters, the improvement comprising the addition of (B) 0.1-10 weight percent, based on the weight of the components (A) and (B), of a silane which contains epoxy groups.
Claim 3
Dependent Claim
23 words
A resin as claimed in claim 1 wherein (A) is composed of methyl methacrylate, butyl methacrylate and acrylic acid and (B) is γ-glycidoxypropyltrimethoxysilane.
Claim 4
Dependent Claim
43 words
A resin as claimed in claim 2 wherein (A) is composed of methyl methacrylate, butyl methacrylate and acrylic acid in a ratio of 16:80:4 and (B) is present in an amount of 0.4 weight percent based on the weight of (A) and (B).
Claim 5
Dependent Claim
93 words
An improved resin for resin finishing textiles, fibers and paper which is a composition of matter which consists essentially of 90-99.9 weight percent of (A) which is a copolymeric organic resin which is prepared from an unsaturated organic acid and an ester selected from a group consisting of (i) acrylic acid esters and (ii) methacrylic acid esters, the improvement comprising the addition of (B) 0.1-10 weight percent of a silane which contains epoxy groups, the amount of (A) and (B) being based on the total weight of (A) and (B) in the composition.
Claim 6
Dependent Claim
93 words
An improved resin for resin finishing textiles, fibers and paper which is a composition of matter which consists essentially of 90-99.9 weight percent of (A) which is a copolymeric organic resin which is prepared from an unsaturated organic acid and an ester selected from a group consisting of (i) acrylic acid esters and (ii) methacrylic acid esters, the improvement comprising the addition of (B) 0.1-10 weight percent of a silane which contains epoxy groups, the amount of (A) and (B) being based on the total weight of (A) and (B) in the composition.
Claim 7
Dependent Claim
23 words
A resin as claimed in claim 4 wherein (A) is composed of methyl methacrylate, butyl methacrylate and acrylic acid and (B) is γ-glycidoxypropyltrimethoxysilane.
Claim 8
Dependent Claim
43 words
A resin as claimed in claim 5 wherein (A) is composed of methyl methacrylate, butyl methacrylate and acrylic acid in a ratio of 16:80:4 and (B) is present in an amount of 0.4 weight percent based on the weight of (A) and (B).
