Abstract

This organic silicon compound is characterized by being represented by structural formula (1), and has good reactivity while having a monoalkoxysilyl group.

(In the formula, X represents a monovalent to trivalent organic group including a polyoxyalkylene structure, an alkylene group having 1-20 carbon atoms, O, S, N, or the like, R 1 and R 2 each independently represent an alkyl group or the like having 1-10 carbon atoms, Y represents a single bond, O, S, or the like, A 1 , A 2 , A 3 , A 4 , and A 5 each represent a single bond, or a divalent linking group such as a divalent hydrocarbon group having 1-20 carbon atoms, and n represents a number of 1-3.)

First claim

The invention claimed is:

1. An organosilicon compound having the structural formula (3):

wherein
R 1 is a substituted or unsubstituted C 1 -C 10 alkyl group, or a substituted or unsubstituted C 6 -C 10 aryl group,
R 2 is each independently a substituted or unsubstituted C 1 -C 10 alkyl group, or a substituted or unsubstituted C 6 -C 10 aryl group, and
R 5 is an unsubstituted C 1 -C 10 alkylene group.

2. A method for preparing the organosilicon compound of claim 1 , comprising the step of reacting a compound having the structural formula (9):

wherein R 5 is as defined above, with a compound having the formula (8):

wherein R 1 and R 2 are as defined above, and R 7 is a leaving group selected from among chlorine, bromine, iodine, methansulfonate, trifluoromethanesulfonate, and p-toluenesulfonate, or a (meth)acryloyloxy group.

3. A curable composition comprising the organosilicon compound of claim 1 .

4. The curable composition of claim 3 , further comprising a curing catalyst.

5. The curable composition of claim 4 wherein the curing catalyst is an amine base compound.

6. A coating agent comprising the curable composition of claim 3 .

7. An adhesive comprising the curable composition of claim 3 .
