<p><P>PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition exhibiting improved fluidity without detriment to impact resistance and a manufacturing method of a polyester resin suitable for alloying a polycarbonate resin. <P>SOLUTION: The resin composition comprises a polycarbonate (A) and a block copolymer (B) having a polyhydroxycarboxylic acid structure unit (I) and a polyester structure unit (II) obtained by causing a dicarboxylic acid to react with a diol. The manufacturing method of the block copolymer (B) comprises causing a compound having the polyhydroxycarboxylic acid structure unit (I) to previously react with a compound having the polyester structure unit (II) obtained by causing a dicarboxylic acid to react with a diol, and subsequently causing the obtained copolymer to react with a compound having a carbodiimide structure. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
