POLIESTERES QUE PUEDEN OBTENERSE POR CONDENSACION DE: (A) ACIDOS CARBOXILICOS CON, AL MENOS, 2 GRUPOS CARBOXILICOS, SUS ESTERES, ANHIDRIDOS O MEZCLAS, (B) COMO MINIMO, ACOHOLES DIVALENTES Y/O LOS PRODUCTOS DE ADICION DE 1 A 5 MOL DE, COMO MINIMO, UN OXIDO DE ALQUILENO CON 2 A 3 ATOMOS DE C CON 1 MOL DE, COMO MINIMO, UN ALCOHOL DIVALENTE, O SUS MEZCLAS Y (C) PRODUCTOS DE ACOPLAMIENTO DE 5 A 80 MOL, COMO MINIMO, DE UN OXIDO DE ALQUILENO CON 1 MOL DE UN ALCOHOL DE 8 A 24 ATOMOS DE C, FENOLES ALQUILICOS DE 6 A 18 ATOMOS DE C O ALQUILAMINAS DE 8 A 24 ATOMOS DE C, EN UNA PROPORCION MOLAR DE (A):(B):(C) DE 100:(25 A 2500):(5 A 110) A TEMPERATURAS DE 120 C COMO MINIMO, HASTA PESOS MOLECULARES (MEDIA EN PESO) DE 2000 A 50000. PROCEDIMIENTO PARA LA PRODUCCION DEL POLIESTER Y UTILIZACION DEL MISMO EN CANTIDADES DE 0,05 A 15% EN PESO COMO ADITIVO INHIBIDOR DE AGRISAMIENTO O AUXILIAR DE DESPRENDIMIENTO DE SUCIEDAD PARA DETERGENTES. Polyesters obtainable by condensation of (a) an at least dicarboxylic acid, or an ester or anhydride or a mixture thereof, (b) an at least dihydric alcohol or an addition product of from 1 to 5 mol of at least one alkylene oxide of 2 or 3 carbon atoms with 1 mol of an at least dihydric alcohol, or a mixture thereof, and (c) a water-soluble addition product of from 5 to 80 mol of at least one alkylene oxide with 1 mol of a C8-C24-alcohol, a C8-C18-alkylphenol or a C8-C24-alkylamine in a molar ratio of (a):(b):(c) of 100:(25-2500):(5-110) at not less than 120 DEG C. up to a weight average molecular weight of from 2000 to 50000, are used in amounts of from 0.05 to 15% by weight as grayness inhibitors and soil release promoters in detergents.
