Title: Method for quenching of polycarbonate and compositions prepared thereby
IPC: C08L69/00
Filed: 2000-04-26
Abstract: Polycarbonate produced by melt condensation of a diaryl carbonate and a dihydric phenol in the presence of a basic catalyst to produce an intermediate polycarbonate composition is finished by quenching with both an alkyl tosylate quencher and phosphorous acid. The efficiency of quenching can be measured by UV retention. Surprisingly, although phosphorous acid alone has no impact on the UV retention, the combination of alkyl tosylate quenchers and phosphorous acid provides a significant improvement over the use of the alkyl tosylate quencher alone. Thus, the method of the invention permits a reduction in the amount of alkyl tosylate quencher used, and can achieve superior results which cannot be achieved even by increasing the alkyl tosylate levels.

Abstract: PURPOSE: To change a random number seed without a non-volatile memory whenever an operation is started. CONSTITUTION: An oscillator 14 is operated immediately after power source supply and generates a high speed clock. A counter 15 is operated by the high speed clock and changes a count value into the high speed one. In the meantime, a power-on reset circuit 10 outputs a power-on reset signal which indicates that an internal power source is made to be stable when a sufficient time elapses after power source supply. The power-on reset signal is sufficiently slower than the high speed clock and a period for an input to a latch circuit 16 is various. Then the count value (the random number seed) to be latched by the latch circuit 16 becomes different whenever the power source is supplied. A random number is generated through the use of the random number seed.
