    Abstract: The invention relates to copolymers which contain alkylene oxide units and also contain the following constituents that are incorporated by polymerization in a statistical or block-by-block manner: (a) 50 to 93 mol % of acrylic acid and/or of a water-soluble salt of the acrylic acid; (b) 5 to 30 mol % of methacrylic acid and/or of a water-soluble salt of the methacryl ic acid, and; (c) 2 to 20 mol % of at least one non-ionic monomer of formula (II), in which the variables have the following meanings: R1 represents hydrogen or methyl; R2 represents a chemical bond or unbranched or branched C1- C6 alkylene; R3 represents identical or different unbranched or branched C2- C4 alkylene groups; R4 represents unbranched or branched C1-C6 alkyl, and; n ranges from 3 to 50. These copolymers are used as an additive in detergents and cleansers.

    Abstract: La presente invencion se relaciona con el uso de un copolimero que comprende, en forma polimerizada, (a) de 80 a 99.9% molar, basado en la cantidad total de los monomeros polimerizados para preparar el copolimero, de cuando menos un monomero A que en cada caso comprende un heterociclo que tiene cuando menos 1 atomo de nitrogeno y compuesto de 3 a 10 miembros de anillo y un grupo alquenilo de C2-C6 enlazado a un atomo de anillo de carbono o nitrogeno del heterociclo; y (b) de 0.1 a 20% molar, basado en la cantidad total de los monomeros polimerizados para preparar el copolimero, de cuando menos un monomero B copolimerizable con el monomero A, el monomero B teniendo un enlace doble monoetilenicamente insaturado y tambien un grupo de oxido de polialquileno de C2-C4 lineal o ramificado que tiene como promedio de 4 a 500 unidades de oxido de alquileno de C2-C4, en formulaciones de detergente liquidas y solidas. Ademas, la invencion se relaciona con un proceso para preparar dicho copolimero, y tambien con una formulacion de detergente liquida o solida que comprende cuando menos uno de dicho copolimero.
