Abstract: Removable protective film (A) on a surface comprises at least a polymer (70 wt.%), based on the total quantity of all the components of the layer, containing at least two different polymers containing ethene (65 wt.%), where (A) is bounded with oxygen bonded carbon and the oxygen content of (A) increases with the increase in the distance to the surface. An independent claim is included for a method for applying (A) on a surface comprising treating the surface with n aqueous formulation (F i) of polymers (where n is >= 2 and i is 1 to n) comprising at least one ethene (65 wt.%) exhibiting oxygen bonded carbon; where the oxygen is optionally bonded to either polymer or to additional components of the formulation and the content of the oxygen bound to carbon in F iincreases with the increase in i.

Abstract: Procedimiento para la obtención de estructuras planas absorbentes, en el que se aplican pegamento y agente absorbente sobre un material soporte, caracterizado porque A) se genera una mezcla a partir de un pegamento que se presenta como dispersión y un agente absorbente en forma de partículas se genera una mezcla mediante fluidizado de los componentes, B) la mezcla de pegamento y el agente absorbente se aplica simultáneamente sobre la superficie de un lado de un primer material soporte plano, C) un lado de un segundo material soporte plano se aplica sobre la mezcla de pegamento y agente absorbente, que se encuentra sobre la superficie de un lado del primer material soporte plano, mediante lo cual se obtiene un producto intermedio de tipo sándwich, y D) el producto intermedio de tipo sándwich se elabora para dar el producto final a una temperatura de al menos 90ºC, una presión de 4 a 50 bar, y un tiempo de prensado de 0, 5 a 5 minutos.

Abstract: A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.
