    摘要： The invention relates to surface-modified particles, more particularly inorganic-based particles having reactive surfaces, more particularly surfaces containing silane-reactive and/or siloxane-reactive groups, preferably hydroxyl-containing surfaces and/or particles comprising or consisting of metal and/or semi-metal oxides and/or hydroxides, preferably nanoparticles, which on their surface have a polysiloxane-based modifier having more particularly been reacted on their surface with a polysiloxane-based modifier, preferably with the formation of chemical bonds, more particularly covalent bonds, and also to a method of producing these surface-modified particles.

    摘要： The invention concerns the use of cerium dioxide, especially in the form of discrete cerium dioxide particles with particle sizes in the range from 0.005 to 150 μm, as inorganic radical trap to stabilize organic polymers, especially in the form of polymer-based formulations, varnishes, paints, coating compounds, or the like, against their photochemically, thermally, physically and/or chemically induced degradation by free radicals, especially against the effect of UV, advantageously in an optional combination with at least one UV-absorber and/or at least one additional radical trap. The radical-induced degradation of the organic polymers is effectively prevented by the use of cerium dioxide without the cerium dioxide itself becoming degraded. If a combination of cerium dioxide with an additional UV-absorber or radical trap is used, its effectiveness is extended through the presence of the cerium dioxide.

    摘要翻译： 本发明涉及使用二氧化铈，特别是二氧化铈颗粒形式，粒径范围为0.005-150μm的二氧化铈颗粒，作为稳定有机聚合物的无机基团捕获剂，特别是以聚合物为基础的配方，清漆的形式 ，涂料，涂料化合物等，其光自由基，热，物理和/或化学诱导的自由基降解，特别是抗紫外线的作用，有利地与至少一种UV吸收剂的任选组合和/或 至少一个额外的激进陷阱。 有机聚合物的自由基诱导的降解通过使用二氧化铈而没有二氧化铈本身变质而被有效地防止。 如果使用二氧化铈与另外的紫外吸收剂或自由基捕获剂的组合，则其有效性通过二氧化铈的存在而延长。
