Abstract: A liquid precursor for the production of fluorine doped tin oxide coatings including 60 to 90% by weight of at least one chlorinated organotin derivative, 5 to 30% by weight of at least one organotin mono(fluoroalkanoate), and 0 to 15% by weight of a tetraorganotin compound. Using vapor phase deposition, this produces a coating with low surface resistance and a high light transmission coefficient. Deposition is effected quickly so the precursor can readily be used to coat a moving substrate, for example, float glass.

Abstract: A process for producing an acrylic and/or methacrylic polymer based preparation for the surface treatment of zinc consists in polymerizing at least one (meth)acrylic acid and at least one (meth)acrylate in a mixture of organic cosolvents. The preparation is then formed from the resultant copolymer in the cosolvents by dilution in a quantity of water and preferably an excess of water with respect to the cosolvents in the polymerization stage.

Abstract: A method for preparing thienylacetic acid and its derivatives is disclosed, wherein a glyoxylic ester is made to react with hydrazine, and after with potash. Advantageously, the glyoxylic ester is prepared by condensation of a monoester monochloride of oxalic acid upon a thiophenic derivative, in the presence of titanium chloride.The so obtained products are useful as organic synthesis intermediaries for various products of pharmaceutical type.
