    • Polyvinyl chloride and polyvinylidene chloride compositions with or without plasticizers are stabilized against heat and light by addition of a dihydrocarbon tin borate of formula (R2Sn)3-n(R1)2n(BO3)2 where R and R1 are alkyl, aryl or aralkyl groups (R1 being an alcohol or phenol residue) and n is 0, 1 or 2. Specified stabilizers include dibutyl tin borate and a compound of formula (C4H9)2Sn(C8H17)4 (BO3)2 prepared from dibutyl tin oxide, 2-ethyl hexanol and boric acid. A composition comprising polyvinyl chloride, di-2-ethylhexyl-phthalate and dibutyl tin borate is described.ALSO:The invention comprises dihydrocarbontin borates of formula wherein R-R1 are alkyl, aryl or aralkyl radicals and n is 0, 1 or 2. They may be prepared by reacting a dihydrocarbontin oxide with boric acid or a partial ester of boric acid at a temperature between 80 DEG and 140 DEG C. If desired, the oxide, boric acid and an alcohol or phenol may be reacted together. The reagents should be substantially anhydrous. An inert organic solvent (benzene, toluene, xylene) may be used as reaction medium. In an example, dibutyl tin oxide is dried by refluxing with toluene, boric acid added and the mixture heated. On distillation of the toluene dibutyl tin borate remains. The preparation of a compound (C4H9)2Sn(C8H17)4 (BO3)2 from dibutyl tin oxide, 2-ethyl hexanol and boric acid is also described.ALSO:Dihydrocarbontin borates of formula: (R2Sn)3-n (R1)2n (BO3)2 are used as rubber antioxidants and rubber accelerators. In the formula R and R1 are alkyl, aryl or aralkyl groups (R1 being the residue of an alcohol or phenol) and n is O, 1, or 2. Specified compounds include dibutyltin borate and a compound of formula (C4H9)2Sn (C8H17)4 (BO3)2 derived from dibutyltin oxide, 2-ethylhexanol and boric acid.

    • Compositions for protecting materials from growth of pestiferous organisms, and particularly for protecting marine surfaces from fouling organisms, are formed from precursors having the formula ##STR1## where m is from 1 to about 10, where each X is independently selected from the group consisting of alkyl and alkoxyalkyl radicals containing less than about 6 carbon atoms and Y, where Y has the formula ##STR2## where R.sub.1, R.sub.2 and R.sub.3 are independently selected from the group consisting of alkyl, cycloalkyl, and aryl radicals, where R.sub.1, R.sub.2 and R.sub.3 contain in combination up to about 18 carbon atoms. The ratio of the tin atoms to silicon atoms in the precursors is at least about 1:50.The precursors can be directly used as an additive for coatings. The precursors can also be used by subjecting them to hydrolysis and polycondensation to form an organotin substituted polysiloxane for use as an additive and a binder for coatings.
