    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.

    Abstract: The method involves introducing the polymer into oil stores. The water-soluble polymer is used in the form of a dispersion of the water-soluble polymer as well as at least one water-soluble polymer stabilizer. The viscosity of the dispersion in the neutral and basic pH region is higher than in the acidic region.
