Abstract: The present invention relates to a liquid hydrosilicone resin and a preparation process thereof. The average composition of the liquid hydrosilicone resin is represented by the following formula: (R1R2R3SiO1/2)M.(R4R5SiO2/2)D. (R6SiO3/2)T.(SiO4/2)Q wherein R1 to R6 are identical or different radicals independently selected from the group consisting of organic groups and a hydrogen atom, with the proviso that at least one of R1to R6 is a hydrogen atom bonded directly to a silicon atom. The liquid hydrosilicone resin is obtained by dispersing a hydrosilicone oil, a hydroxyl silicone resin and a dehydrogenation catalyst in a solvent to form a dispersion, allowing the dispersion to react, and then removing the solvent and the catalyst.

Abstract: A solvent-free and anhydrous hardenable composition that contains at least one polymer A. Polymer A being obtainable by reacting a polyether with at least one ethylenically unsaturated silane in the presence of a radical starter, the ethylenically unsaturated silane carrying at least one hydrolyzable group on the silicon atom.

Abstract: A method for stabilizing particulate peroxycarboxylic acids, in particular imidoperoxycarboxylic acids, (such as, e.g., PAP), which are solid at an ambient temperature in a preferably aqueous dispersion containing surfactants. The dispersion is established in such a way that in the dispersed state a degradation of the peroxycarboxylic acids in the dispersion is prevented or at least reduced or retarded, or that the solubility of the peroxycarboxylic acids in the dispersion is diminished, in particular by minimizing the halide ion content, reducing the pH value to pH values ?7, minimizing the content of free or active surfactants, minimizing the content of non-ionic surfactants, adding complexers, adding catalases or adding a solvent with a low solubility capability for peroxycarboxylic acids etc.
