Abstract
An organosilicon compound represented by formula (1). (R1 is an alkyl, alkenyl, aryl, or acyl group, R2 is an alkyl or aryl group, R3 is a hydrogen atom or a methyl group, A1 is a single bond or an alkylene group, A2, A3, and A4 are each a methylene group or an oxygen atom, with the proviso that at least one of the A2, A3, and A4 moieties is an oxygen atom, and n is an integer of 1-3.)
Claims10
An organosilicon compound of formula (1) below
- wherein each R1 is independently an alkyl group of 1 to 10 carbon atoms, an alkenyl group of 2 to 10 carbon atoms, an aryl group of 6 to 10 carbon atoms or an acyl group of 1 to 20 carbon atoms;
- each R2 is independently an alkyl group of 1 to 10 carbon atoms or an aryl group of 6 to 10 carbon atoms;
- R3 is a hydrogen atom or a methyl group;
- A1 is a single bond or a substituted or unsubstituted divalent hydrocarbon group of 1 to 20 carbon atoms;
- A2, A3 and A4 are each independently a substituted or unsubstituted methylene group or oxygen atom, with the proviso that one or more of A2, A3 and A4 is an oxygen atom and no oxygen atoms are mutually adjoining;
- and
- n is an integer from 1 to 3.
