    摘要： The present invention relates to weathering-stable mixtures for preparing organic-inorganic (hybrid) transparent topcoat materials. The hybrid composition comprises an inorganic binder based on polyfunctional organosilanes which contain at least 2 silicon atoms having in each case 1 to 3 alkoxy or hydroxyl groups, the silicon atoms being attached by in each case at least one Si—C bond to a structural unit that links the silicon unit; (semi)metal alkoxides and/or hydrolysis and concentration products of these; inorganic UV absorbers selected from the group consisting of ZnO and CeO2; an organic polyol; and one or more solvents.

    摘要： The present invention relates to a process for preparing aliphatic oligocarbonate polyols having secondary OH groups and number-average molecular weights ≧500 g/mol, by A) initially reacting excess amounts of organic carbonates with polyols which have exclusively primary OH groups via a transesterification reaction to prepare an intermediate polymer having an average concentration of OH groups of ≦0.3 mol %, based on 1 mol of the intermediate polymer, B) removing the cleavage products formed simultaneously with the transesterification reaction or subsequently together with excess unconverted carbonate, and, in a further step, C) reacting the intermediate polymer with aliphatic polyols which each have at least one secondary OH group per molecule to obtain aliphatic oligocarbonate polyols having an average of ≧5 mol % of secondary OH groups, based on the total of all the OH groups present. The present invention also relates to coatings, dispersions, adhesives or sealants obtained using these aliphatic oligocarbonate polyols.
