    • A process for preparing a siloxane compound comprising a 2-hydroxyphenyl benzotriazole function which comprises at least one step in which a reaction for hydrosilylation of a compound 2-hydroxyphenyl benzotriazole comprising a substituent having a terminal double bond with a siloxane compound comprising an SiH function is carried out in the presence of a catalyst and of at least one volatile organic solvent corresponding to one of formula (VII) or (VIII). in which R4 and R5, which may be identical or different, represent a linear or branched C1-C4 alkyl radical, with the proviso that the sum of the carbons of R4 and R5 is less than or equal to 6; y is and integer between 1 and 3; R6 which may be identical or different, are linear or branched C1-C3 alkyl radicals, with the proviso that the sum of the carbons of R6 is less than or equal to 6 is disclosed.
    • 一种制备包含2-羟基苯基苯并三唑功能的硅氧烷化合物的方法,其包含至少一个步骤,其中包含具有末端双键的取代基的化合物2-羟基苯基苯并三唑与包含SiH官能团的硅氧烷化合物的氢化硅烷化反应是 在催化剂和对应于式(VII)或(VIII)之一的至少一种挥发性有机溶剂的存在下进行。 其中可以相同或不同的R 4和R 5表示直链或支链C 1 -C 4烷基,条件是R 4和R 5的碳的总和小于或等于6; y为1和3之间的整数; 可以相同或不同的R 6是直链或支链C 1 -C 3烷基,条件是R6的碳原子总数小于或等于6。
