Abstract
Organic silicon compounds having an alkoxy group at one end and an alkali metal salt of sulfonic acid or sulfuric acid at the other end are novel. They can be obtained by effecting hydrosilylation reaction between an alkoxyhydro-silane and a compound having an alkenyl group at one end and an alkali metal salt of sulfonic acid or sulfuric acid at the other end. They are useful as a modifier and surface treating agent.
Claims10
An organic silicon compound of the following general formula (1):
- ##STR16## wherein R.sup.1 is an alkyl group, R.sup.2 is an alkylene group having at least 3 carbon atoms, R.sup.3 is an alkylene group having at least 2 carbon atoms, R.sup.4 is an oxygen atom or divalent hydrocarbon group containing an oxygen atom, M is an alkali metal, letter m is a number of 1 to 3, n is a number of 3 to 60, and p is equal to 0 or 1.
A process for preparing an organic silicon compound of the following formula (1):
- ##STR17## wherein R.sup.1 is an alkyl group, R.sup.2 is an alkylene group having at least 3 carbon atoms, R.sup.3 is an alkylene group having at least 2 carbon atoms, R.sup.4 is an oxygen atom or divalent hydrocarbon group containing an oxygen atom, M is an alkali metal, letter m is a number of 1 to 3, n is a number of 3 to 60, and p is equal to 0 or 1, said process comprising the step of effecting hydrosilylation reaction between a compound of the following formula (2):
- ##STR18## wherein R.sup.1 and m are as defined above and a compound of the following formula ( 3):
- ##STR19## wherein R.sup.3 R.sup.4, M, n and p are as defined above, and R.sup.5 is a hydrogen atom or methyl group.
