    • The present invention relates to a process for performing a controlled hydrolysis and condensation of an epoxy-functional silane of the general formula I R1-SiR′m(OR)3-m (I) in which R1 is a (III) or (IV) group and R, R′ and R″ groups are the same or different and are each hydrogen (H) or a linear, branched or cyclic, optionally substituted alkyl group having from 1 to 6 carbon atoms, A and A′ groups are the same or different and are each a bivalent alkyl group having from 1 to 10 carbon atoms, R2 groups are the same or different and R2 is a linear, branched or cyclic, optionally substituted alkyl group having from 1 to 20 carbon atoms, and m is 0 or 1, and optionally of at least one further organofunctional silane of the general formula II R2-SiR′n(OR)3-n (II) in which R2 is an organofunctional group as already defined above, R′ is methyl, R groups are each independently hydrogen or a linear, branched or cyclic alkyl group having from 1 to 6 carbon atoms and n is 0 or 1, where from 0.001 to ≦5 mol of water is used per mole of alkoxy function of the silanes used, no further hydrolysis or condensation catalyst is used apart from boric acid as the hydrolysis catalyst and condensation component, and the condensates formed in the reaction are based on Si—O—B— and/or Si—O—Si bonds.
    • 本发明涉及一种通式I R 1 -Si R'm(OR)3-m(I)的环氧官能硅烷进行受控水解和缩合的方法,其中R 1是(III)或(IV )基团,R,R'和R“基团相同或不同,各自为氢(H)或具有1至6个碳原子的直链,支链或环状,任选取代的烷基,A和A'基团为 相同或不同,各自为具有1至10个碳原子的二价烷基,R 2基团相同或不同,并且R 2为具有1至20个碳原子的直链,支链或环状的任选取代的烷基,m为 0或1,以及任选地至少一种另外的通式为R 2 -SiR'n(OR)3-n(II)的有机官能硅烷,其中R 2是如上定义的有机官能团,R'是甲基,R 基团各自独立地为氢或具有1至6个碳原子且n为0或1,w的直链,支链或环状烷基 这里为0.001至< nlE;每摩尔使用的硅烷的烷氧基官能度使用5摩尔的水,除了作为水解催化剂和缩合组分的硼酸之外不再使用进一步的水解或缩合催化剂,反应中形成的缩合物 基于Si-O-B和/或Si-O-Si键。
