The effect is greater for the six-membered ring imide unit. Regarding the content of (D) units and (E) units, the (D) units are 0.1 to 48% by weight, preferably 1 to 3% by weight, based on the copolymer.

ド単位の定量は元素分析による窒素分定置去を月いる。The most common method for quantifying the five types of repeating units (A) to (E) in the copolymer of the present invention is a method using an infrared spectrophotometer. In particular, the methyl methacrylate unit is characterized by absorption at 1730 cm-', and the six-membered cyclic acid anhydride unit is 1g0f1cm-'
and 1760 cm-' absorption. In the six-membered ring imide unit, the N-substituted product has a distinct absorption at 1670c+n-', and the methyl methacrylate unit has a distinct absorption at 1730c+
Although it can be distinguished from ++-', the N-substituted 1700 cm
-' absorption is 1730 of the methyl methacrylate unit.
It is difficult to separate from cm-'. Therefore, the determination of the six-membered ring imide unit requires determination of the nitrogen content by elemental analysis.
