Claims
- 1. A process for producing a silicon-containing comb-shaped polymer comprising a unit of the formula (I): ##STR13## wherein R.sup.1 is an alkylene having 1 to 4 carbon atoms, R.sup.2, R.sup.3, and R.sup.4 are the same or different and are each an alkyl having 1 to 4 carbon atoms, R is hydrogen atom or methyl, X.sup.1 is hydroxycarbonyl, an alkoxycarbonyl having 2 to 5 carbon atoms, a cycloalkyloxycarbonyl having 3 to 8 carbon atoms in the cycloalkyl moiety or phenyl, n is 1 to 100,000R.sup.5 is an alkyl having 1 to 4 carbon atoms or phenyl, X.sup.2 is an alkyl having 1 to 4 carbon atoms and containing one to three groups selected from --NH.sub.2 and fluorine, l is 2 to 20, and m is 0 to 1 to 10, which comprises polymerizing a vinyl monomer of the formula: ##STR14## wherein R and X.sup.1 as defined above by using a mercaptosilane compound of the formula: ##STR15## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are as defined above as a chain transfer agent in an amount of 0.01 to 5 parts by weight to 100 parts by weight of the vinyl monomer (III) to obtain a macromonomer of the following formula (II) which has a dialkoxysilyl group at the terminus: ##STR16## wherein R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, X.sup.1 and n are as defined above, and polycondensing the macromonomer (II), wherein the polycondensation of the macromonomer (II) is carried out together with a dialkoxysilane compound of the formula: ##STR17## wherein R.sup.5 and X.sup.2 are as defined above, and R.sup.6 and R.sup.7 are the same or different and are each an alkyl having 1 to 4 carbon atoms.
- 2. The process according to claim 1, wherein the polymerization of the vinyl monomer (III) is carried out in the presence of a radical initiator.
- 3. The process according to claim 1, wherein the polycondensation of the macromonomer (II) is carried out in the presence of a polycondensation catalyst.
- 4. The process according to claim 1, wherein X.sup.2 is a group selected from 3,3,3-trifluoropropyl and 3-amino-propyl.
