摘要：

<P>PROBLEM TO BE SOLVED: To provide a resin composition having good heat stability and excellently balanced properties such as phase difference-expressing tendency. <P>SOLUTION: The present invention is attained by modulating the ratio of hydrogen and methyl group bound to a carbon adjacent to a carbonyl group in the resulting imide resin. In particular, the imide resin is obtained by treatment with an imidating agent of a methacrylic resin, in which the number of the acrylic acid alkyl ester unit in the methacrylic acid alkyl ester/acrylic acid alkyl ester copolymer is <1%. <P>COPYRIGHT: (C)2011,JPO&INPIT
