preparation example Construction
[0076] The preparation of most of the above epoxy-terminated silane compounds is described in US Patent No. 3,131,161.
[0077] Other useful epoxy-terminated silanes are epoxy-terminated silanes represented by the formula:
[0078]
[0079] in
[0080] m is 1 to 6 (preferably 1 to 4),
[0081] n is 0 or 1 (preferably 1),
[0082] p is 1 to 6 (preferably 1 to 4), and
[0083] R 1 is H or an alkyl group of 1 to 10 carbon atoms (preferably an alkyl group of 1 to 4 carbon atoms).
[0084] In addition to any of the aforementioned epoxysilanes, partially hydrolyzed or condensed epoxysilanes which are further curable upon exposure to light in the presence of a photoacid generator may also be used in the present invention, alone or in combination with unhydrolyzed epoxysilanes. These partial hydrolysates can be obtained by silane OR 1 Formed by partial hydrolysis of the group. Thus, the term "precondensate" includes siloxanes in which some or all of the silicon atoms are bon...
