Insertion of copper(II)/Schiff-Base complexes with NLO properties into commercial polycarbonates by thermal processes

The preparation of a bisphenol-A carbonate copolymer, containing Cu-diime units with nonlinear optical (NLO) properties, and its MALDI-TOF mass spectrometric characterization are reported. Contrary to the usual synthetic method, NLO groups were inserted directly into a commercial polycarbonate by prolonged heating at 250degreesC. This innovative procedure allows to obtain a Cu/diimine-containing polymer of high molecular weight
