Claims18
A molten product which is (1) a product obtained by melt-mixing 1 to 99 parts by weight of a wholly aromatic polyester carbonate comprising 50 to 99 mol % of a recurring unit represented by the following formula (I):
- 13
- wherein A1 and A2are the same or different and each a substituted or unsubstituted aromatic group,
- and 50 to 1 mol % of a recurringunit represented by the following formula (ii):
- 14
- wherein A3 is a substituted or unsubstituted aromatic group, with 99 to 1 part by weight of an aromatic polycarbonate, the total amount of the wholly aromatic polyester carbonate and the aromatic polycarbonate being 100 parts by weight, and which has (2) a total light transmittance of a 2 mm-thick plate molded therefrom of more than 85% and (3) a yellow index (YI) value based on JIS K7103 of 28 or less.
