Abstract:
A polyoxaamide copolymer comprising a polyoxaamide copolymer having a first divalent repeating unit of formula IA:[--X'--C(O)--R.sub.30 --C(O)--] IAa second divalent repeating unit of the formula IB:[X--C(O)--C(R.sub.1)(R.sub.2)--O--R.sub.3 --O--C(R'.sub.1)(R'.sub.2)--C(O)--] IBand a third repeating unit selected from the group of formulas consisting of:[--Y--R.sub.17 --].sub.T II[--O--R.sub.5 --C(O)--].sub.B, III[--O--R.sub.9 --C(O)].sub.P --O--).sub.L G XIand combinations thereof, wherein R.sub.30 is an alkylene, arylene, arylalkylene, substituted alkylene, substituted arylene and substituted alkylarylene provided that R.sub.30 cannot be --[C(R.sub.1)(R.sub.2)].sub.1--2 --O--R.sub.3 --O--[C(R'.sub.1)(R'.sub.2)].sub.1--2 --; X, X' and Y are selected from the group consisting of --O-- and --N(R)--, provided that X, X' and Y cannot both be --O--; R, R.sub.1, R'.sub.1, R.sub.2 and R'.sub.2 are independently selected from the group consisting of hydrogen and an alkyl group containing 1 to 8 carbon atoms; R.sub.3 is selected from the group consisting of an alkylene unit and an oxyalkylene group of the following formula: ##STR9## wherein C is an integer in the range of from 2 to about 5, D is an integer in the range of from 0 to about 2,000, and E is an integer in the range of from about 2 to about 5, except when D is zero, in which case E will be an integer in the range of from 2 to 12; R.sub.17 is an alkylene unit containing from 2 to 8 carbon atoms which may have substituted therein an internal ether oxygen, an internal --N(R.sub.18)-- or an internal --C(O)--N(R.sub.21)--; T is an integer in the range of from 1 to 2,000; R.sub.18 and R.sub.21 are independently selected from the group consisting of hydrogen and an alkyl group containing 1 to 8 carbon atoms; R.sub.5 and R.sub.9 are independently selected from the group consisting of --C(R.sub.6)(R.sub.7)--, --(CH.sub.2).sub.3 --O--, --CH.sub.2 --CH.sub.2 --O--CH.sub.2 --, --CR.sub.8 H--CH.sub.2 --, --(CH.sub.2).sub.5 --, --(CH.sub.2).sub.F --O--C(O)-- and --(CH.sub.2).sub.K --C(O)--CH.sub.2 --; R.sub.6 and R.sub.7 are independently selected from the group consisting of hydrogen and an alkyl containing from 1 to 8 carbon atoms; R.sub.8 is selected from the group consisting of hydrogen and methyl; F and K are independently selected integer in the range of from 2 to 6; B is an integer in the range of from 1 to n such that the number average molecular weight of formula III is less than about 200,000; P is an integer in the range of from 1 to m such that the number average molecular weight of formula XI is less than about 1,000,000; G represents the residue minus from 1 to L hydrogen atoms from the hydroxyl groups of an alcohol previously containing from 1 to about 200 hydroxyl groups; and L is an integer from about 1 to about 200.
