Abstract

PURPOSE: To obtain the titled copolymer useful as a sensitized resist for fine processing, etc., having improved adhesivity to substrates, heat resistance, and good resolving power, by subjecting a specific hydroxystyrene and a specified maleimide by the use of a radical initiator to alternating copolymerization in the presence of water.
CONSTITUTION: (A) A hydroxystyrene shown by the formula I (R1WR3 are H, or 1W4C alkyl; R6 is H, aralkyl, or acetyl; Z is 1W4C alkyl; m3' is 0, 1, 2, or 3) is copolymerized with (B) a maleimide shown by the formula II (R4 and R5 are H, or 1W4C alkyl; R7 is H, 1W10C alkyl, phenyl, etc.) in a molar ratio of the component A to B of 10:90W90:10 by the use of a radical initiator, light rays, heat, radiation, etc. at 0W120°C when a solvent contains 2W80% water, at 25W100°C when the solvent contains only ≤2%, or at 50W100°C when it contains ≥80% water and optionally the phenolic nucleus is subjected to substitution reaction, to give a copolymer shown by the formula III (X and Y are halogen, sulfonic acid, nitro, etc.; m1Wm3 are 0W3; n is 3W10,000).
