倍半硅氧烷树脂
摘要：
由下述单元组成的倍半硅氧烷树脂：(Ph(CH2)rSiO(3-x)/2(OR′)x)m，(HSiO(3-x)/2(OR′)x)n ，(MeSiO(3-x)/2(OR′)x)o，(RSiO(3-x)/2(OR′)x)p ，(R1SiO(3-x)/2(OR′)x)q，其中Ph是苯基，Me是甲基；R′是氢原子或具有1-4个碳原子的烃基；R选自芳基磺酸酯基，或芳基磺酸酯基和相当的芳基磺酸基的混合物，条件是在该混合物中，大多数R是芳基磺酸酯基；和R1选自取代的苯基、酯基、聚醚基、巯基、和反应性或可固化的有机官能团；和r的数值为0、1、2、3或4；x的数值为0、1或2；其中在该树脂中，m的数值为0-0.95；n的数值为0.05-0.95；o的数值为0.05-0.95；p的数值为0.025-0.5；q的数值为0-0.5；和m+n+o+p+q＝1。
摘要（英）：

A silsesquioxane resin comprised of the units (Ph(CH2)rSiO(3-x)/2(OR')x)m, (HSiO(3-x)/2(OR')x)n' (MeSiO(3-x)/2(OR' )x)o' (RSiO(3-x)/2(OR')x)p, (R1SiO(3-x)/2(OR')x)q where Ph is a phenyl group, Me is a methyl group; R' is hydrogen atom or a hydrocarbon group having from 1 to 4 carbon atoms; R is selected from an aryl sulfonate ester group; and R1 is selected from substituted phenyl groups, ester groups, polyether groups; mercapto groups, and reactive or curable organic functional groups; and r has a value of 0, 1,2, 3, or 4; x has a value of 0, 1 or 2; wherein in the resin m has a value of 0 to 0,95; n has a value of 0.05 to 0.95; o has a value of 0.05 to 0.95; p has a value of 0.05 to 0.5; q has a value of 0 to 0.5; and m + n + o + p + q = 1.
