专利号:US-6376693-B2 优先权日:2000-08-02 标 题 :Synthesis of organotin oxides 发明人:GROSSMAN RICHARD F 权利人:HAMMOND GROUP INC 摘要:Organotin oxides are synthesized by reacting powdered tin metal with an alcohol at elevated temperatures on the order of about 200-400° C. Monoalkyltin, dialkyltin and trialkyltin oxides are produced in quantitative yields according to the method.
专利号:US-12129358-B2 优先权日:2020-02-24 标题 :Alkyl-bridged tin-based thermal stabilizers for halogenated resins and synthesis and uses thereof 发明人:ROSS KEVIN JOHN; NORRIS GENE KELLY 权利人:PMC ORGANOMETALLIX INC 摘要:The present invention relates to stabilizer composition for halogen-containing polymer. It has recently been found that tin-based thermal stabilizers with a bridging alkyl group between two tin centers are effective stabilizers while having effectively double the molecular weight of the corresponding non-alkyl bridged stabilizer. It is expected that ongoing experimentation will confirm that the alkyl bridged stabilizers have much lower volatility which leads to greater retention of the stabilizer in the finished article.
