Studies of bisphenol-A-polycarbonate aging by Raman difference spectroscopy Academic Article

abstract

• Raman difference spectroscopy (RDS) has been used to measure small frequency shifts (up to 3 cm-1) in the Raman frequencies of the bisphenol-A-polycarbonate polymer when subjected to elongation or thermal aging. While only minor shifts were observed upon thermal treatment, the elongation treatment resulted in shifts of -2.51 0.23 cm-1 for the C-O stretching band at 1235 cm-1 of -0.78 0.15 cm-1 for the CH out-of- plane wag at 885 cm-1. Smaller shifts were also observed for the 1606 and 1111 cm-1 bands. This work demonstrates that conformational processes can be monitored using RDS. (C) 2000 Elsevier Science B.V.
