Definitions
- the invention relates to a process for the absorption of water and water-like compounds in silicone-containing polymers.
- Absorption is understood to mean the uniform penetration of water or water-like compounds into a solid polymer material, the phase boundary essentially being retained. Additionally, polymeric solids may also utilize adsorptive processes, which involve the absorption of water or water-like substances at the polymer surface.
- polysaccharides, proteins, polyvinyl alcohols or polyacrylates act as absorbers of water.
- Examples of application are the absorption of interfering water in solvents, the absorption of body fluids, for example in hygiene articles or in wound dressings.
- Water-absorbent materials are also used for self-sealing of weathered components. Cracks can be occluded by the volume increase triggered by contact with water.
- the examples mentioned show that the absorption of aqueous liquids plays an important role in the art.
- the object of the present invention is to provide a process for the absorption of liquids containing water, which does not have the disadvantages of the prior art mentioned.
- the invention relates to a process for the absorption of liquids (F) containing compounds (V), which
- Weight fraction of oxygen which is present in the form of hydroxy or hydroxyl and ether groups, at least 27%, in solid silicone-containing polymer (P), the at least one Siloxane unit of the general formula I and no or at least one unit of the general formula II
- R 1 and R 2 independently of one another denote hydrogen or an unbranched, branched or cyclic saturated or unsaturated alkyl group having 1 to 20 C atoms or aryl group or aralkyl group, where individual non-adjacent methylene units are represented by groups -O-, -CO-, -COO-, -OCO- or -OCOO-, -S- or NR or may be replaced by an oxyalkylene group of the general formula (-O-CH 2 -CHR 3 ⁇ ) d ,
- R 3 is hydrogen or alkyl
- R x is hydrogen or an unsubstituted or with substituents which are selected from -CN and halogen, substituted Ci-Cio - hydrogen radical,
- X is a radical of the general formula which carries at least one amino acid unit and is bonded via a carbon atom to the silicon atom
- Y is -NR 4 - (CH 2 ) e -CR 5 R 6 -COO
- R 10 independently of one another are hydrogen or C 1 -C 12 -alkyl, aryl or aralkyl,
- R 4 is hydrogen or a linear, branched or cyclic saturated or unsaturated alkyl group having 1 to 20 C atoms or aryl group or aralkyl group, where individual non-adjacent methylene units are represented by groups -0-, - CO, -COO-, -OCO- or -OCOO-, -S- or NR X or can be replaced by an oxyalkylene group of the general formula (-O-CH 2 -CHR 3 -) d ,
- R 5 and R 6 are independently hydrogen or linear
- branched or cyclic saturated or unsaturated alkyl groups having 1 to 20 C atoms or aryl groups or aralkyl groups, wherein individual non-adjacent methylene units represented by groups -O-, -CO-, -COO-, -OCO- or -OCOO-, -S- or NR X may be replaced, where R 5 or R 6 may be connected to R 4 ,
- Y is a linear, branched, cyclic, saturated or mono- or polyunsaturated C x to C 10 o alkylene radical connected via a carbon atom to the organosilicon compound, in which individual carbon atoms can be replaced by oxygen, nitrogen or sulfur atoms and which can not be replaced with adjacent hydroxyl groups may be substituted,
- a 0, 1, 2 or 3
- c 1, 2 or 3
- e have integer values 0 to 50
- liquids (F) are brought into contact with the solid silicone-containing polymer (P).
- Silicones are known as extremely hydrophobic polymer materials. Surprisingly, however, it has been found that the absorption of water and alkanols, their weight fraction of oxygen, in the form of hydroxy or hydroxyl and ether groups
- aqueous liquids advantageously using Silicone-containing polymers (P) containing amino acid groups, can be performed.
- Absorption in the sense of the invention is understood to mean the uniform penetration of liquids (F) into the solid silicone-containing polymer (P), the phase boundary between
- Liquids (F) and silicone-containing polymer (P) is maintained.
- Carboxylic acid groups may be present as a free carboxylic acid or as a carboxylate salt or as mixtures of these.
- the amino moiety may be present both as a free amino group or in protonated form as an ammonium moiety or as a mixture thereof.

- Table 1 Weight gain of the lysine-modified polymer sample from Example 1 on contact with water
- a polymer film was prepared by dissolving the material in ethanol and evaporating the solvent in a mold.
- Polymer film was applied to a slide and placed in water. Depending on the storage period, the weight gain of the polymer material was determined. For this purpose, the präger was taken out of the water, superficially appended water was blown off in the air stream and the
- Weight gain determined. Table 3 shows the weight gain by absorption and the respective factor of weight gain. After 21 days, the original weight had more than quadrupled.
