    Abstract: PROBLEM TO BE SOLVED: To obtain a water-base metal-processing oil contg. water and a mist- preventive copolymer by copolymerizing a specific hydrophobic monomer and a specific hydrophilic monomer. SOLUTION: A hydrophobic monomer being either an alkylate acrylamide compd. represented by formula I (wherein R1 is H or methyl; and R2 and R3 are each H or hydrocarbyl provided their total number of carbon atoms is 2-36) or an acrylic ester represented by formula III (wherein R1 is H or methyl; and R9 is a 1-20C hydrocarbyl) and a hydrophilic monomer selected from among an acrylamidosulfonic acid salt represented by formula III (wherein R4 is H or methyl; and R is a 2-8C aliph. or arom. hydrocarbon group), an acrylamidodisulfonic acid salt represented by formula IV (wherein R4 is H or methyl; and R is a 2-8C aliph. or arom. hydrocarbon group), and a styrenesulfonic acid salt represented by formula V (wherein X is an alkali or alkaline earth metal caiton, etc.) are subjected to free-radical copolymn.

    Abstract: PROBLEM TO BE SOLVED: To obtain a working fluid which can inhibit mist appearance in metal working application by incorporating water and a copolymer formed from a specific hydrophobic monomer, a specific hydrophilic monomer, and an ethylenically unsatd. branched monomer into the same. SOLUTION: This working fluid contains water and a copolymer which is formed from (A) a hydrophobic monomer comprising an alkyl-substd. acrylamide of formula I and/or an acrylic ester of formula II, (B) a hydrophilic monomer comprising a sulfonic acid (salt) of formula III and/or styrenesulfonic acid or its salt, and (C) an ethylenically unsatd. branched monomer, both the molar ratio of A/B and the amt. of C being specified. In the formulas, R1 is H or CB3 ; R2 and R3 are each H or hydrocarbyl provided the sum of their numbers of carbon atoms is 2 to about 36; R9 is hydrocarbyl or an alkyl- terminated polyether group; X is O or NY; Y is H, 1-18C hydrocarbyl, or -R(-SO3 H)n ; R4 is R1 ; R is a 2 to about 18C aliph. or arom. hydrocarbylene group; and n is 1 or 2. The salt of monomer B is e.g. an alkali or alkaline earth metal salt.

    Abstract: Synthetic alkyl arenesulfonates in combination with the salt of a coupled reaction product of (A)(I) high-molecular weight polycarboxylic acylating agent, said acylating agent (A)(I) having at least one hydrocarbyl substituent having an average of from about 20 to about 500 carbon atoms, and at least one (B)(I) low-molecular weight polycarboxylic acylating agent, said acylating agent (B)(I) optionally having at least one hydrocarbyl substituent having an average of about 6 to about 19 carbon atoms, being coupled together by (C) at least one compound having (i) two or more primary amino groups, (ii) two or more secondary amino groups, (iii) at least one primary amino group and at least one secondary amino group, (iv) at least two hydroxyl groups or (v) at least one primary or secondary amino group and at least one hydroxyl group. These salt compositions are useful as emulsifiers in oil-in-water emulsions useful as functional fluids.
