Abstract
Reaction of PC with 2-hydroxy-4-(2-hydroxyethoxy)benzophenone (HHEBP) was carried out in the presence of FeCl3 in a torque rheometer at 255°C. The reaction rapidly proceeded and conversion was more than 80% within 5 min. HHEBP reacted quantitatively except for the amount of HHEBP vaporized. A film of this product showed high weather-proof on weather-o-test when compared to typical PC with no benzophenone derivatives or PC containing HHEBP obtained by the control experiment.
