Systematic changes in the intensity of the methacrylate C=C stretching mode at 1638 cm-1 as a function of exposure duration were observed. The calculated degree of conversion (DC) ranged from 45.0% (B) to 52.0% (T) and from 49.0% (B) to 55.0% (T) for the LED and halogen lamp, respectively. LED and halogen light produced similar DC values with 40 and 60 s of irradiation.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-12T12:08:23Z No. of bitstreams: 1 23643.pdf: 310083 bytes, checksum: 009080165773fd75a54a21081419ad2e (MD5)Made available in DSpace on 2011-12-12T12:08:23Z (GMT).
