Abstract: This invention provides one-pot reaction for digesting polycarbonate waste with alkylene glycol in the presence of a basic catalyst at 180° C. under normal atmospheric pressure. The digested product mixture was found to consist of bisphenol A (BPA) and monoalkoxylated and bisalkoxylated diols of BPA. Alkoxylation of BPA and monoalkoxylated diols of BPA is performed by adding urea or urea derivative (or carbonic acid ester or amine ester) to the digested product mixture at a high temperature under normal atmospheric pressure to obtain the final product, i.e., bisalkoxylated diols of BPA in high yield. The bisalkoxylated diols of BPA may be used as raw materials to synthesize polymer such as polyurethane (PU) or polyester.

Abstract: A series of crosslinkable sulfonated poly(ether ketone)s containing cycloalkenyl groups were synthesized by aromatic nucleophilic substitution reaction. To decrease the swelling of fuel cell membranes, crosslinking of theses polymers by radical polymerization has been explored. These polymeric films exhibit good thermal and oxidative stability, and good dimensional stability in hot water. The proton conductivity of one example at room temperature is 7.52*10?2 S/cm. The results showed that these materials containing cycloalkenyl groups are possible inexpensive candidate materials for proton exchange membranes in fuel cell applications.

Calibration is made through the calibrator prior to audio system reproduction, wherein the frequency control circuit provides a reference frequency and different test frequencies for causing the signal generator to generate respective sound signals for output through a speaker; the microphone picks up these sound signals for comparison with respective reference values by the compare circuit; and the display circuit displays the respective comparison results. By means of adjustment through respective adjust circuits, signals of test frequencies are standardized so that the music played through the audio system is well calibrated without sound spectrum distortion due to space or audio system discrepancy.
