Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A composition suitable for use in the treatment of glass fibers which comprises a polyester polymer having a molecular weight of greater than 1000 and comprising units of the formulae ##STR4## wherein R is a divalent hydrocarbon radical, R° is an alkyl, aryl, or aralkyl group, X is alkoxy, hydroxy, or divalent oxygen, y is 0 or 1, v is an integer of from 1 to 6, z is 2, 1, or 0, a is 0 or a mole fraction of from 0.004 to 0.6, b and e are mole fractions ranging from about 0.004 to about 0.6, and d is a mole fraction ranging from 0.4 to 0.6, with the proviso that d is greater than, equal to, or slightly less than the sum of a, b, and e, and An is anion of a monovalent acid, and from 10 weight % to 100 weight %, based upon the weight of said polyester polymer in the composition, of a polyalkylene oxide polymer of the formula EO[CH.sub.2 CH.sub.2 O].sub.m [CH(CH.sub.3)CH.sub.2 O].sub.n H wherein E is hydrogen or an alkyl end-blocking group having up to 8 carbon atoms, m ranges from 0 to 50, n ranges from 0 to 20, and m+n must total at least 3.
Claim 2
Dependent Claim
206 words
A composition suitable for use in the treatment of glass fibers which comprises a polyester polymer having a molecular weight of greater than 1000 and comprising units of the formulae ##STR4## wherein R is a divalent hydrocarbon radical, R° is an alkyl, aryl, or aralkyl group, X is alkoxy, hydroxy, or divalent oxygen, y is 0 or 1, v is an integer of from 1 to 6, z is 2, 1, or 0, a is 0 or a mole fraction of from 0.004 to 0.6, b and e are mole fractions ranging from about 0.004 to about 0.6, and d is a mole fraction ranging from 0.4 to 0.6, with the proviso that d is greater than, equal to, or slightly less than the sum of a, b, and e, and An is anion of a monovalent acid, and from 10 weight % to 100 weight %, based upon the weight of said polyester polymer in the composition, of a polyalkylene oxide polymer of the formula EO[CH.sub.2 CH.sub.2 O].sub.m [CH(CH.sub.3)CH.sub.2 O].sub.n H wherein E is hydrogen or an alkyl end-blocking group having up to 8 carbon atoms, m ranges from 0 to 50, n ranges from 0 to 20, and m+n must total at least 3.
