Abstract
There are prepared sulfur containing organoorganooxysilanes of the formula A-X-Z where A is R-S--, where R is a triazine or thiodiazole residue, X is a divalent organic residue, Z is -SiR" (OR').sub.2 ; -Si(OR').sub.3 ; -Si(OR').sub.2 -O-Si(OR').sub.3 ; -Si(OR').sub.2 -O-Si(OR').sub.2 -X-A; where R' and R" are alkyl groups of 1 to 12 carbon atoms. The compounds are useful as additives to cross-linkable mixtures containing organic polymers.
