A maleimide copolymer comprising maleimide monomer units, aromatic vinyl monomer units and other vinyl monomer units and having the following characteristics, and a maleimide resin composition comprising the above copolymer and a rubbery graft polymer: I) the content of residual maleimide monomer in the copolymer is 0.1 wt. % or less, and the total content of volatiles other than the maleimide monomer is 0.5 wt. % or less; II) the content of a compound obtained from at least one monomer selected from the group consisting of a maleimide monomer, aromatic vinyl monomers and other vinyl monomers and having a weight-average molecular weight of 200 to 1,000 as determined by gel permeation chromatography is 2-10 wt. %; III) the copolymer has a yellow index of 30 or less; and IV) the copolymer has an intrinsic viscosity of 0.3 to 1.5.

apoptosis. We report herein a new construct, EA‐BPS, that contains both a brominatedBODIPYphotosensitizer (BPS) and an ethacrynicacid (EA) GST‐pi inhibitor. Photoirradiation of EA‐BPS induces a synergistic antitumor effect that results from the combination of ROS production and GST‐pi inhibition. Relative to BPS alone, an enhanced cell‐killing effect is seen under hypoxic conditions both in vitro and
