    Abstract: A stable aqueous polymer emulsion (I) comprises: (A) polyolefin oxylates; (B) aminofunctionalized polyorganosiloxanes; (C) non-ionic emulsifiers comprising a mixture of alkoxylated higher alkanols, water and optionally additives and processing aids. A stable aqueous polymer emulsion (I) comprises: (A) polyolefin oxylates of formula (1); (B) aminofunctionalized polyorganosiloxanes of formula (2); (C) non-ionic emulsifiers comprising a mixture of alkoxylated higher alkanols, water and optionally additives and processing aids. [Image] R1>H or lower alkyl; R2>H, -COOH or another oxygen containing functional group, alkyl, alkenyl or cyclohexyl optionally substituted by -COOH or another oxygen containing functional group or R1> and R2> together have oxygen; R3>lower alkyl or alkoxy; R4>OH or R3>; Z : aminoalkyl; r : 30-200; s : 50-300; t : 1-4. An independent claim is included for a process for the preparation of the emulsion (I) by mixing components of (A) and (C) in a melt at 100-150 [deg]C; mixing the melt with an aqueous component solution at 85-100 [deg]C such that it is finely distributed; addition of component (B) followed by homogenizing at room temperature.

    Abstract: Aqueous alkyldiketene dispersions which contain a C14-C22-alkyldi- ketene and from 1 to 10% by weight of a polymeric protective col- loid contain, as the protective colloid (a) copolymers of (1) N-vinylpyrrolidone and (2) at least one quaternized N-vinylimidazole or a substi- tuted quaternized N-vinylimidazole as polymerized units in a molar ratio of from 80:20 to 5:95 and have a K value of at least 20 (according to H. Fiken- tscher in 0.5 M aqueous sodium chloride solution at a polymer concentration of 0.1% by weight and at 25.degree.C) or (b) condensates which are obtainable by (1) partial amidation of polyethyleneimines with monocarbox- ylic acids and, if required (2) condensation of the partially amidated polyethyleneimines with at least bifunctional crosslinking agents Which have a halohydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as a functional group to give crosslinked, amidated polyethyleneimines which have a viscosity of at least 100 mPa.s in 20% strength by weight aqueous solution at 20.degree.C, or mixtures of (a) and (b) and are used as engine size in the production of paper, board and cardboard and for rendering cellu- losic fibers water-repellent.

    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.
