Abstract: PURPOSE:To obtain a low-discolored polycarbonate resin useful for glass sheets, etc., by reducing the amount of a specific compound in the resin without using toxic phosgene. CONSTITUTION:This polycarbonate resin is obtained by polycondensation through melt transesterification between a dihydric phenol and carbonic diester in the presence of acidic compound(s) (pref. boric acid and/or ammonium hydrogenphosphite) and using a transesterification catalyst [pref. basic catalyst, more pref., nitrogen-contg. basic compound or alkali (alkaline earth) metal compound]. It is preferable that this resin have the following characteristics: p-hydroxyacetophenone content:

Abstract: PURPOSE:To efficiently produce a colorless high-mol.-wt. polycarbonate by cooling, in an inert gas flow, a high-mol.-wt. polycarbonate melt obtd. by a specific melt polycondensation method. CONSTITUTION:A dihydroxy compd. [e.g. a compd. of formula I, II, III, or IV (wherein R1 to R4 are each H, 1-8C alkyl, or phenyl; X is halogen; n is 0-4; and m is 1-4)] is polycondensed in melt with a bisaryl carbonate (e.g. bisphenyl carbonate) by transesterification to give a polycarbonate resin melt, which is cooled by blowing to it an inert gas below the temp. of the resin melt. Thus, the surface of the resin is cooled to a temp. not allowing the oxidation of the surface and an almost colorless high-mol.-wt. polycarbonate resin is obtd.

Abstract: PURPOSE:To obtain as high-mol.-wt. polycarbonate substantially free from chloride ion without using phosgene by polycondensing a dihydric phenol with a carbonic diester in the presence of a (substd.) phenylacetic acid catalyst. CONSTITUTION:A dihydric phenol [e.g. a compd. of formula II, III, IV, or V (wherein R1 to R4 are each H, 1-8C alkyl, or phenyl; X is halogen; n is 0-4; and m is 1-4)] is polycondensed with a carbonic diester in the presence of a catalyst selected from among an optionally substd. phenylacetic acid of formula I (wherein R1 is H, 1-5C alkoxy, or NO2; and R2 and R3 are each H, 1-5C alkyl, or phenyl). Thus is produced a transparent, colorless high-mol.-wt. polycarbonate substantially free from chloride ion without using phosgene.

Abstract: PURPOSE:To obtain a polycarbonate having faint color and useful for injection molding at a low cost by carrying out the melt polycondensation of a bivalent hydroxy compound and a bisaryl carbonate in a reactor plated at the liquid- contacting part. CONSTITUTION:A polycarbonate is produced by the ester-interchange melt- polycondensation of a bivalent hydroxy compound (e.g. bisphenol A) and a bisaryl carbonate in the presence of an ester interchange catalyst (e.g. lithium borohydride). The reactor used in the above reaction has a liquid-contacting part plated with Cr or Ni or the reactor is made of a stainless steel and has a liquid-contacting part subjected to electrolytic polishing.
