Abstract:
A copolymer based on unsaturated dicarboxylic acid derivatives and oxyalkylene glycol alkenyl ethers comprising:a. 1 to 90 mol. % of at least one member selected from the group consisting of structural units of Formula Ia and Formula Ib: ##STR6##wherein M is independently H, a monovalent cation; a bivalent cation, and ammonium ion or an organic amine;a=1/2 or 1;R.sup.1 is independently --O.sub.a M or --O--(C.sub.m H.sub.2m O).sub.n --R.sup.2, wherein R.sup.2 is selected from the group consisting of H, a C.sub.1 to C.sub.20 aliphatic hydrocarbon, a C.sub.5 to C.sub.8 cycloaliphatic hydrocarbon, substituted C.sub.6 to C.sub.14 aryl, and unsubstituted C.sub.6 to C.sub.14 aryl; wherein m is 2 to 4 and n is 1-200;b. 0.5 to 80 mol. % of the structural units of Formula II ##STR7##wherein R.sup.3 is independently H, a C.sub.1 to C.sub.5 aliphatic hydrocarbon; p is 0 to 3 and R.sup.2, m and n are defined as above;c. 0.5 to 80 mol. % of structural units selected from the group consisting of Formula IIIa and IIIb ##STR8##wherein R.sup.4 is independently selected from the group consisting of H, a C.sub.1 to C.sub.20 aliphatic hydrocarbon that may be substituted with at least one hydroxyl group, a C.sub.5 to C.sub.8 cycloaliphatic hydrocarbon, and a C.sub.6 to C.sub.14 aryl which may optionally be substituted with a member selected from the group consisting of --COO.sub.a M, --(SO.sub.3).sub.a M, --(PO.sub.3).sub.a M.sub.2 ; --(C.sub.m H.sub.2m O).sub.n --R.sup.2, and --CO--NH--R.sup.1 ; wherein M, a, R.sup.2, m and n are defined as above; andd. 1.0 to 90 mol. % of structural units of Formula IV ##STR9##wherein R.sup.5 is independently H, methyl or a possibly substituted methylene group, which, together with R.sup.7 forms one or more 5- to 8-membered rings;R.sup.6 is independently H, methyl or ethyl; andR.sup.7 is independently H, a C.sub.1 to C.sub.20 aliphatic hydrocarbon, a C.sub.5 to C.sub.8 cycloaliphatic hydrocarbon, a C.sub.6 to C.sub.14 aryl which may be substituted; --OCOR.sup.4, --OR.sup.4, --OOR.sup.4, wherein R.sup.4 is defined as above.
