  A process for the preparation of polycarbonate by the phase interface process is disclosed. The process includes (a) preparing a sodium hydroxide solution by chloralkali electrolysis, the solution containing not more than 30 ppm sodium chlorate relative to the weight of sodium hydroxide, and (b) reacting an aqueous solution of said sodium hydroxide with at least one dihydoxydiarylalkane to obtain a solution of disodium salt and (c) reacting said solution of disodium salt with phosgene in the presence of at least one organic solvent, a chain terminator and optionally a branching agent to obtain an oligocarbonate, and (d) condensing the oligocarbonate in the presence of at least one catalyst to obtain a material system containing polycarbonate and organic solvent and (e) separating off of the organic phase from said material system. The polycarbonate prepared by the inventive process is characterized by its low yellowness index.

• A method of making an abrasion resistant coating on a solid substrate and articles produced thereby
  申请人：FOSTER GRANT CORPORATION

  公开号：EP0101326A1

  公开（公告）日：1984-02-22

  There is disclosed a method for providing an improved abrasion resistant coating on solid substrates such as plastic articles and solid articles prepared thereby having on the surface such abrasion resistant coating. A solid substrate is coated with an organosilanol-type coating liquid comprising organosilanol molecules or a partial condensation product thereof. At least 90 mole percent of said organosilanol molecules are trifunctional silanol molecules of the formula RSi(OH)3, R being a hydrocarbon radical, and at least 50 mole percent of said trisilanols being an alkyl trisilanols of 1-3 carbon atoms or phenyl trisilanol. Preferably, at least 70 mole percent of the trisilanol is methyltrisilanol. After the coating is cured by a conventional means, it is post-treated by a glow discharge to afford an abrasion resistance far superior to those obtained from organosilanol coating liquids without glow discharge post-treatment. There is also disclosed a mirrored solid substrate such as a plastic sheet having an improved abrasion resistance which comprises a layer of a glow discharge treated organosiloxane coating and a mirror layer deposited thereon.
