    • PURPOSE: A novel carbosiloxane dendrimer having a highly branched structure in which the siloxane bond and silalkylene bond alternate is provided which can be used as an admixture and surfactant for various organic resins. CONSTITUTION: A dendrimer of formula 1 has a narrow molecular weight distribution and 1 non-radically-polymerizable substituted hydrocarbon group in the molecule. In formula, Y is a non-radically-polymerizable substituted hydrocarbon group, R1 is C1-10 alkyl or aryl, b is 0 to 50, c is 1 to 3, X1 is a silylalkyl group of formula 2 represented by Xi (i is 1). When the carbosiloxane dendrimer contains a condensation-reactive group as the non-radically-polymerizable group, the carbosiloxane dendrimer is useful as a modifier for organic resins and paints.
    • 目的:提供具有高度支化结构的新型碳硅氧烷树枝状聚合物,其中硅氧烷键和硅烷撑键交替,可用作各种有机树脂的混合物和表面活性剂。 构成:式1的树枝状大分子在分子中具有窄的分子量分布和1个非自由基聚合的取代的烃基。 式中,Y为非自由基取代烃基,R1为C1-10烷基或芳基,b为0〜50,c为1〜3,X1表示由Xi表示的式2的甲硅烷基烷基(i为 1)。 当碳硅氧烷树枝状大分子含有缩合反应性基团作为非自由基聚合性基团时,碳硅氧烷树枝状聚合物可用作有机树脂和涂料的改性剂。
