Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
71 words
A process for treating textile substrates comprising the steps of 1) impregnating the substrate with an emulsion polymer comprising: a) 80-99.5% by weight of a vinyl ester; b) 0-20% by weight of a mono-ethylenically unsaturated copolymerizable comonomer; c) 0.5 to 5% by weight of a polyethylenically unsaturated comonomer; d) 0 to 6% by weight of a post-crosslinking comonomer; and 2) drying the coated substrate by contact with a heated metal surface.
Claim 2
Dependent Claim
71 words
A process for treating textile substrates comprising the steps of 1) impregnating the substrate with an emulsion polymer comprising: a) 80-99.5% by weight of a vinyl ester; b) 0-20% by weight of a mono-ethylenically unsaturated copolymerizable comonomer; c) 0.5 to 5% by weight of a polyethylenically unsaturated comonomer; d) 0 to 6% by weight of a post-crosslinking comonomer; and 2) drying the coated substrate by contact with a heated metal surface.
Claim 3
Dependent Claim
42 words
The process of claim 1 wherein the polyethylenically unsaturated comonomer is selected from the group consisting of lower alkenyl lower alkenoates, di-lower alkenyl alkanedioates, di- or tri-lower alkenyl benzenedicarboxylates, lower alkanediol di- or tri-lower alkenoates, lower alkylene bisacrylamides and lower alkylene bis-methacrylamides.
Claim 4
Dependent Claim
16 words
The process of claim 2 wherein the polyethylenically unsaturated comonomer is triallyl cyanurate or diallyl maleate.
Claim 5
Dependent Claim
21 words
The process of claim 1 wherein the polyethylenically unsaturated comonomer is added in an amount of 1.0 to 1.5% by weight.
Claim 6
Dependent Claim
12 words
The process of claim 1 wherein the vinyl ester is vinyl acetate.
Claim 7
Dependent Claim
28 words
The process of claim 1 wherein the mono-ethylenically unsaturated copolymerizable comonomer is selected from the group consisting of (meth)acrylates, maleates, (meth)acrylic acid, ethylene, vinyl chloride and vinyl versatate.
Claim 8
Dependent Claim
26 words
The process of claim 1 wherein the post-crosslinking comonomer is an N-alkylolamide of an alpha beta ethylenically unsaturated carboxylic acid having 3 to 10 carbon atoms.
Claim 9
Dependent Claim
12 words
The process of claim 7 wherein the post-crosslinking comonomer is N-methylol acrylamide.
Claim 10
Dependent Claim
58 words
In a process for treating textile substrates with a vinyl ester based emulsion polymer containing 80-99.5% by weight vinyl ester and subsequently drying the substrate by contact with a heated metal roll, the improvement which comprises interpolymerizing 0.5 to 5% by weight of a polyethylenically unsaturated cross-linking comonomer into the vinyl ester emulsion prior to treating said substrates.
Claim 11
Dependent Claim
58 words
In a process for treating textile substrates with a vinyl ester based emulsion polymer containing 80-99.5% by weight vinyl ester and subsequently drying the substrate by contact with a heated metal roll, the improvement which comprises interpolymerizing 0.5 to 5% by weight of a polyethylenically unsaturated cross-linking comonomer into the vinyl ester emulsion prior to treating said substrates.
