Abstract (en)
[origin: WO2009147020A1] Compositions containing between 50 and 99.999% of an organopolysiloxane/polyurea/polyurethane block copolymer of the general formula (1), containing between 0.001% and 10% of a UV absorber, which are compatible with the polymer of the general formula I, the concentration of free amino groups or isocyanate groups in the polymer (I) being smaller than 40 mmol/kg, where R is a monovalent hydrocarbon group with 1 to 20 carbon atoms that is optionally substituted with fluorine or chlorine, X is an alkylene group with 1 to 20 carbon atoms, in which non-neighboring methylene units can be substituted with -O- groups, A is an oxygen atom or an amino group -NR'-, Z is an oxygen atom or an amino group -NR'-, R' is hydrogen or an alkyl group with 1 to 10 carbon atoms, Y is a bivalent hydrocarbon group with 1 to 20 carbon atoms that is optionally substituted with fluorine or chlorine, D is an alkylene group with 1 to 700 carbon atoms that is optionally substituted with fluorine, chlorine, C1-C6 akyl ester or C1-C6 alkyl ester, in which non-neighboring methylene units can be substituted with -O-, -COO-, -OCO-, or - OCOO- groups, B is hydrogen or a functional or non-functional organic or silicon-organic group, n is a number from 1 to 1000, a is a number of at least 1, b is a number from 0 to 40.15, c is a number from 0 to 30 and d is a number greater than 0.
