Abstract
There is disclosed a composition comprising approximately by weight (a) 0.01 to 0.1% of a copolymer of (1) an ethylenically unsaturated polymeric anhydride or partial ester and (2) an ethylenically unsaturated monomer; (b) up to 10% of at least one lower alkylene glycol lower alkyl monoether, (c) up to 25% of an aliphatic alcohol; (d) 0.1 to 2% of an ethoxylated C.sub.10.sub.-18 alkali metal sulfate and the balance water. Components (b) and (c) may both be present, or a greater amount of one to compensate for the absence of the other.

A composition consisting essentially of approximately by weight, (a) 0.01 to 1.% of a copolymer derived from (1) an .alpha., .beta. - ethylenically unsaturated dicarboxylic acid anhydride having the general formula ##EQU4## wherein R and R' are independently selected from the group consisting of hydrogen, alkyl, aryl, aralkyl, substituted alkyl, aryl and aralkyl and (2) an ethylenically unsaturated monomer selected from the group consisting of vinyl ethers, styrene, alpha-methyl styrene, lower alkyl substituted styrenes and lower olefins, up to 10% of at least one lower alkylene glycol;
- lower alkyl monoether, (c) up to 25% of a C.sub.1 -6 aliphatic alcohol, (d) 0.1 to 2.0% of an ethoxylated C.sub.10 -18 alkali metal or ammonium sulfate having about 2-200 units of ethylene oxide and the balance water, with the proviso that at least one of component (b) or (c) is present.
A stable concentrate consisting essentially of approximately (a) 0.01 to 10 parts of a copolymer derived from (1) an .alpha., .beta. -- ethylenically unsaturated dicarboxylic acid anhydride having the general formula ##EQU5## wherein R and R' are independently selected from the group consisting of hydrogen, alkyl, aralkyl, substituted alkyl, aryl and aralkyl and (2) an ethylenically unsaturated monomer selected from the group consisting of vinyl ethers, styrene, alpha-methyl styrene, lower alkyl substituted styrenes and lower olefins, (b) 0-10 parts of at least one lower alkylene glycol lower alkyl monoether, (c) 0-10 parts of a C.sub.1 -6 aliphatic alcohol and (d) 0.1 to 0.9 parts of an ethoxylated C.sub.10.sub.-18 alkali metal or ammonium sulfate having about 2-200 units of ethylene oxide.
