    Abstract: The invention relates to a defoamer and/or deareator on the basis of oil-in-water dispersions which, in the hydrophobe oil-phase, contain 3-thiaalkane-1-oles, 3-thiaoxide-alkane-1-oles, 3-thiadioxide-alkane-1-oles, esters of the compounds mentioned or the mixtures thereof as defoaming and/or deairing compounds. The invention also relates to the use of 3-thiaalkane-1-oles, 3-thiaoxide-alkane-1-oles, 3-thiadioxide-alkane-1-oles, esters of the compounds mentioned or the mixtures thereof as defoamers and/or deareators.

    Abstract: La presente invencion se refiere a las dispersiones acuosas de alquildiceteno que contienen una alquildiceteno de C14-C y de 1 a 10% por peso de un coloide protector polimérico que contiene, como coloide protector, (a) copolímeros de (1) N-vinilpirrolidona y (2) por lo menos un N-vinilimidazol cuaternizado o N-vinilimidazol cuaternizado sustituido. Como unidades polimerizadas en una relacion molar desde 80:20 a 5:95 y que tiene un valor K de por lo menos 20 (determinado de acuerdo con H. Fikentscher en una solucion de cloruro de sodio acuso 0.5 M a una concentracion del polímero de 0.1% por peso y a 25 degree C), o (b) condensados que sean obtenibles mediante (1) amidacion parcial de polietileniminas con ácidos monocarboxílicos, y si se requieren. (2) La condensacion de las polietieliniminas parcialmente amidadas con agentes de reticulacion por lo menos bifuncionales que tengan una unidad halohidrina, glicidilo, aziridina o isocianato o un átomo de halogeno como grupo funcional. Para dar polietileniminas amidadas reticuladas que tienen una viscosidad de por lo menos 10 mPa.s en concentracion de 20% por peso de la solucion acuosa a 20 degree C, o una mezcla de (a) y (b), y se utilizan como apresto de máquina en la produccion de papel, carton y cartoncillo para volver recipientes al agua las fibras celulosicas.
