    摘要： Branched, soluble, high-molecular-weight, thermoplas­tic polycarbonates having improved properties, and, in particular, suitable to the fabrication by blow-moulding, characterized by the presence in their structure of units deriving from the use in the synthesis of tris(4'-hydrox­yaryl)-amino-S-triazines having the formula: wherein R₁ and R₂, equal to, or different from each other, indicate hydrogen, linear or branched C 1-5 alkyl, or halogen (in particular, chlorine and bromine).

    摘要： Homo- and copolycarbonates of spirobiindane bisphenols are prepared by first reacting phosgene with a substantially pure spirobiindane bisphenol in the presence of aqueous base in a heterogeneous medium at a pH in the range of about 9-11, and subsequently adding an interfacial polycarbonate formation catalyst and, optionally, a dihy­droxyaromatic compound and a chain termination agent and continuing phosgene passage at a pH of at least about 10. By this method, there may be prepared homo- and copolycar­bonates of 6,6'-dihydroxy-3,3,3',3'-tetramethyl-1,1-spiro­(bis)indane having high molecular weight. Said homopoly­carbonates and copolycarbonates with bisphenol A may be used for manufacture of optical disks having low birefringence.

    摘要： This invention relates to polycarbonates formed at least in part from dihydroxy aryl ketones and optionally benzylic hydrogen-containing aromatic diols. These polycarbonates may be formed, molded, or otherwise incorporated into articles which upon exposure to electromagnetic radiation causes the formation of crosslinking bonds therby imparting improved solvent resistance to the completed structure.
