Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
76 words
In an adduct for application to a textile article for the purpose of improving the functional performance of the article, the improvement consisting essentially of including in the adduct and chemically bonding therein about from 5 to 50 weight percent of a durabilizing organic moiety having a melting point between about 100° and about 300°C. and a Solubility Parameter differing by at least one unit from the Solubility Parameter of the functional component of the adduct.
Claim 2
Dependent Claim
76 words
In an adduct for application to a textile article for the purpose of improving the functional performance of the article, the improvement consisting essentially of including in the adduct and chemically bonding therein about from 5 to 50 weight percent of a durabilizing organic moiety having a melting point between about 100° and about 300°C. and a Solubility Parameter differing by at least one unit from the Solubility Parameter of the functional component of the adduct.
Claim 3
Dependent Claim
31 words
An adduct of claim 1 further comprising about from 5 to 35 percent by weight of the adduct of a linking segment having at least two groups reactive with active hydrogen.
Claim 4
Dependent Claim
16 words
An adduct of claim 1 wherein the durabilizing component has from 1 to 10 repeating units.
Claim 5
Dependent Claim
9 words
An adduct of claim 1 further comprising polyethylene glycol.
Claim 6
Dependent Claim
24 words
An adduct of claim 1 wherein the durabilizing organic moiety is selected from polyesters, polyurethanes and polyamides of from 1 to 10 repeating units.
Claim 7
Dependent Claim
30 words
An adduct of claim 1 wherein the functional component thereof imparts at least one property selected from oil and water repellency, soil release, antistatic properties, durable press, and water repellency.
Claim 8
Dependent Claim
31 words
An adduct of claim 6 wherein the functional component of the adduct comprises at least 15 weight percent of the adduct and consists essentially of a polyfluorinated oil and water repellent.
Claim 9
Dependent Claim
18 words
An adduct of claim 7 wherein the functional component is derived from an ethoxylated long chain aliphatic alcohol.
Claim 10
Dependent Claim
59 words
An adduct of claim 1 formed by bringing into contact under reaction conditions oligomeric ethylene glycol terephthalate hexa(methoxymethyl)melamine, polyethylene glycol having a molecular weight of from 550 to 2,000 and R--O(C 2 H 4 O) n H wherein R is a straight chain alkyl group of from 10 to 16 carbon atoms and n has from 10 to 20.
Claim 11
Dependent Claim
47 words
An adduct of claim 1 prepared by bringing into contact under reaction conditions oligomeric ethylene glycol terephthalate hexa(methoxymethyl)melamine, C n F 2n +1 CH 2 CH 2 OH where n is from 4 to 14 and polyethylene glycol having a molecular weight of from 200 to 2,000.
