Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 148 words
A polyureaurethane polymer prepared by reacting urea with an equal molar amount of a mixture of an amino alcohol and a diamine at a temperature from 150°C to 220°C, wherein the mixture contains from 10 to 90% by weight of a diamine and from 90 to 10% by weight of amino alcohol, wherein the amino alcohol has the formula H 2 N(RO) m (CHR"O) n H wherein m is 0 or 1, n an integer from 2 to 14, R is an alkylene group having from 3 to 5 carbon atoms, and each R is independently hydrogen or methyl, and wherein the diamine has the formula H.sub.2 H --RO--.sub.m --CH.sub.2 CHR"O--.sub.q CH.sub.2 CHR"-- NH.sub.2 wherein m is 0 or 1, q is an integer from 2 to 13, R is an alkylene radical having from 3 to 5 carbon atoms and each R" is independently hydrogen or methyl.
Claim 2
Dependent Claim 148 words
A polyureaurethane polymer prepared by reacting urea with an equal molar amount of a mixture of an amino alcohol and a diamine at a temperature from 150°C to 220°C, wherein the mixture contains from 10 to 90% by weight of a diamine and from 90 to 10% by weight of amino alcohol, wherein the amino alcohol has the formula H 2 N(RO) m (CHR"O) n H wherein m is 0 or 1, n an integer from 2 to 14, R is an alkylene group having from 3 to 5 carbon atoms, and each R is independently hydrogen or methyl, and wherein the diamine has the formula H.sub.2 H --RO--.sub.m --CH.sub.2 CHR"O--.sub.q CH.sub.2 CHR"-- NH.sub.2 wherein m is 0 or 1, q is an integer from 2 to 13, R is an alkylene radical having from 3 to 5 carbon atoms and each R" is independently hydrogen or methyl.
