| titleOfInvention | Trivinyltin hydroxide and a process for its preparation |
| abstract | Trivinyl-tin hydroxide forms copolymers with vinyl chloride, styrene, vinyl silanes, methyl methacrylate and acrylates. It may also be used as a stabilizer in polyvinyl chloride compositions, as may be epoxyethyl tin hydroxide obtained from it by epoxidizing the unsaturated linkage(s).ALSO:The invention comprises trivinyl tin hydroxide which is prepared by reacting trivinyltin chloride or bromide with a basic compound in aqueous solution containing sufficient hydroxyl ions to replace all the halogen atoms by hydroxide. Specified bases include sodium and potassium hydroxides, carbonates and bicarbonates, ammonium hydroxide, aniline, pyridine, morpholine, tetraalkyl - ammonium hydroxides, calcium oxide and hydroxide and barium hydroxide. The trivinyltin chloride and bromide may react with the aqueous solution in the pure state, or it may react in solution in an inert hydrocarbon or organic solvent (e.g. benzene, toluene, pentane, hexane, cyclohexane, an alcohol or ether). An inert atmosphere such as nitrogen may be maintained during the reaction if desired. Epoxyethyl tin hydroxides may be obtained by epoxidizing the unsaturated linkages in trivinyltin hydroxide. |
