摘要： A modified solid polyalkylaluminoxane is provided, which is capable of providing α-olefin suppressing adhesion of any polymer produced as a by-product onto the reactor wall and the stirrer, and which is capable of providing a highly active olefin oligomerization reaction catalyst. An olefin oligomerization reaction catalyst containing the modified solid polyalkylaluminoxane is also provided. The modified solid polyalkylaluminoxane for olefin oligomerization reactions contains structural units represented by general formula (a) and structural units represented by general formula (b), whose median diameter is equal to or larger than 0.1 μm and equal to or smaller than 50 μm, in which R′ in the general formula (a) represents an alkyl group having 1 to 20 carbon atoms, and R″ in the general formula (b) represents a halogenated alkoxy group having 1 to 20 carbon atoms or a halogenated aryloxy group having 6 to 20 carbon atoms.

摘要： A method for coupling tin-containing molecules via a Sn--Sn bond is described. The invention employs dehydrocondensation to link the Sn atoms of two molecules to form tin dimers as well as novel high molecular weight organotin polymers. In a preferred embodiment, catenated tin polymers are formed from hydrostannane precursors in the presence of a suitable metal catalyst. A particularly preferred method involves coupling dialkylstannane monomers in the presence of a metallocene catalyst to form polystannanes. Preferred catalysts include electropositive metals, such as Zr and Hf. The polystannanes are photolabile, decomposing readily under room light conditions.

摘要： CORROSION OF METAL SURFACESIN C ONTACT WITH THERMOPLASTIC POLYMER COMPOSITIONS CONTAINING HALOGENATED HYDROCARBON FLAME RETARDANTS IS SUBSTANTIALLY REDUCED BY THE ADDITION OF ORGANOTIN SALTS OF MERCAPTO-SUBSTITUTED C ARBOXYLIC ACIDS. COLOR OF THE POLYMER COMPOSITION IS IMPROVED BY THE USE OF ORGANOTIN SALTS OF OLEFINICALLY UNSATURATED DIACIDS. INCLUSION OF BOTH TYPES OF ORGANOTIN COMPOUNDS BOTH INHIBITS CORROSION AND STABILIZES POLYMER COLOR.
