Zusammenfassung: | Provided is an ultraviolet-absorbing polycarbonate which exhibits excellent heat resistance as well as excellent weather resistance without showing a reduction in its performance or contaminating a processing facility during processing. The ultraviolet-absorbing polycarbonate is represented by the following Formula (1):
[wherein, n represents an integer of 2 to 300; B 1 represents a linear or branched alkylidene group having 2 to 10 carbon atoms or the like; R 1 to R 4 each independently represent a hydrogen atom or the like; and A 1 and A 2 each independently represent a group represented by the following Formula (2), (3) or the like:
(wherein, G 1 represents a linear or branched alkylene group having 1 to 18 carbon atoms or the like; R 5 to R 8 each represent a linear or branched alkyl group having 1 to 12 carbon atoms or the like; R 9 and R 10 each represent a linear or branched alkyl group having 1 to 12 carbon atoms or the like; and R 11 represents a hydrogen atom or the like)
(wherein, R 12 and R 13 each represent a hydrogen atom or the like)]. |
