Use of copolymers containing alkylene oxide units, (meth)acrylic acids or their salts, and nonionic monomer as anti coating washing and cleaning material additives

摘要

The use of copolymers containing alkylene oxide units and (mole%): (a) acrylic acid and/or one of its a water soluble (50-93), (b) methacrylic acid and/or one of its a water soluble salts (5-30), and (c) at least one nonionic monomer (2-20), statistically or block polymerized as washing and cleaning material additives is new. The use of copolymers containing alkylene oxide units and (mole%): (a) acrylic acid and/or one of its water soluble salts (50-93); (b) methacrylic acid and/or one of its a water soluble salts (5-30); and (c) at least one nonionic monomer (2-20) of formula (I). R1 = H or Me, R2 = chemical bond or optionally branched 1-6C alkylene, R3 = optionally branched 2-4C alkylene, R4 = optionally branched 1-6C alkyl, n = 3-50, statistically or block polymerized as washing and cleaning material additives. An Independent claim is also included for a washing and cleaning material containing the copolymer as a coating inhibiting additive.
