    • The present invention relates to multifunctionalized polyorganosiloxanes comprising, per molecule at least one functional siloxy unit Y having C1-C5 alkoxy radical and at least one other functional siloxy unit W having an halogenated or polyhalogenated alkyl, aralkyl or aryl; polyether ether; epoxidized alkyl; alkoxyalkyl; hydroxylated, carbonylated or esterified alkyl; phenol; and alkoxysilyl; and optionally at least one siloxy unit having a SiH group. The alkoxy functionality Y is introduced onto a suitable polyhydroorganosiloxane by a dehydrogenation/condensation reaction from the alcohol from which Y derives and then the non-hydrogen functionality W by a hydrosilylation reaction from the olefinic compound from which W derives. The multifunctionalized polyorganosiloxanes can be used as antiadhesion modulators in silicone compositions.
    • 本发明涉及多官能化聚有机硅氧烷,其包含每分子至少一个具有C 1 -C 5烷氧基的至少一个官能甲硅烷氧基单元Y和至少一个具有卤代或多卤代烷基,芳烷基或芳基的其它功能性甲硅烷氧基单元W; 聚醚醚; 环氧化烷基; 烷氧基烷基 羟基化,羰基化或酯化烷基; 苯酚; 和烷氧基甲硅烷基; 和任选的具有SiH基团的至少一个甲硅烷氧基单元。 将烷氧基官能团Y通过脱氢/缩合反应引入到合适的多羟基有机硅氧烷上,所述脱氢/缩合反应来自于Y衍生的醇,然后通过来自W衍生的烯烃化合物的氢化硅烷化反应产生非氢官能度W。 多官能化聚有机硅氧烷可用作硅氧烷组合物中的抗粘附调节剂。
