Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A plasticized composition comprising thermoplastic copolyetherester elastomer consisting essentially of recurring linear etherester and ester segments wherein the etherester segments are derived from difunctional polyether glycol and dicarboxylic acid, and the ester segments are derived from organic diol and aromatic dicarboxylic acid and, in an amount from 10 parts per 100 parts polyester segment up to an amount which exudes from the composition, a normally liquid sulfonamide of the formula ##STR10## in which R and R 1 are hydrogen or alkyl of 1-6 carbon atoms, R 2 is alkyl of 1-12 carbon atoms and R, R 1 and R 2 contain a total of at least 2 carbon atoms.
Claim 2
Dependent Claim
109 words
A plasticized composition comprising thermoplastic copolyetherester elastomer consisting essentially of recurring linear etherester and ester segments wherein the etherester segments are derived from difunctional polyether glycol and dicarboxylic acid, and the ester segments are derived from organic diol and aromatic dicarboxylic acid and, in an amount from 10 parts per 100 parts polyester segment up to an amount which exudes from the composition, a normally liquid sulfonamide of the formula ##STR10## in which R and R 1 are hydrogen or alkyl of 1-6 carbon atoms, R 2 is alkyl of 1-12 carbon atoms and R, R 1 and R 2 contain a total of at least 2 carbon atoms.
Claim 3
Dependent Claim
20 words

Claim 4
Dependent Claim
11 words
The composition of claim 2 in which R 1 is alkyl.
Claim 5
Dependent Claim
14 words

Claim 8
Dependent Claim
18 words
The composition of claim 1 containing up to 50 weight percent sulfonamide per total weight sulfonamide and elastomer.
Claim 9
Dependent Claim
16 words
The composition of claim 1 containing 10-40 weight percent sulfonamide per total weight sulfonamide and elastomer.
Claim 10
Dependent Claim
76 words
The composition of claim 1 in which the copolyetherester elastomer consists essentially of recurring linear etherester and ester segments wherein the etherester segments are derived from difunctional polyether glycol having a molecular weight between about 1000 to 4000 and dicarboxylic acid, and the ester segments are derived from organic diol and aromatic dicarboxylic acid and represents a repeating unit of a fiber-forming polyester having a melting point above 200° C in its fiber-forming molecular weight range.
Claim 11
Dependent Claim
30 words
The composition of claim 9 in which the copolyetherester elastomer contains about 30% to about 80% by weight etherester segments and about 70% to about 20% by weight ester segments.
Claim 12
Dependent Claim
20 words
The composition of claim 10 in which the copolyetherester elastomer is derived from terephthalic acid, polytetramethylene ether glycol and 1,4-butanediol.
