Claims14
A process for the preparation of organosilicon polysulfide compounds comprising reacting
- (a) a benzothiazolyl-morpholinyl disulfide compound of the formula ##STR11## with (b) mercaptoalkoxysilane compound of the formula
- Z--R.sup.1 --SH IV
- wherein Z is selected from the group consisting of ##STR12## wherein R.sup.1 is selected from the group consisting of a substituted or unsubstituted alkylene group having a total of 1 to 18 carbon atoms and a substituted or unsubstituted arylene group having a total of 6 to 12 carbon atoms;
- R.sup.2 may be the same or different and is independently selected from the group consisting of an alkyl group having 1 to 18 carbons and phenyl;
- and R.sup.3 may be the same or different and is independently selected from the group consisting of alkoxy groups having 1 to 8 carbon atoms and cycloalkoxy groups with 5 to 8 carbon atoms.
