    • A polymer for forming a radiation sensitive composition is provided to obtain a color filter capable of preventing formation of non-dissolved portions during development and generation of scum at the edge of a pattern, and generating no defects and undercuts even under a low exposure dose. A polymer is obtained by reacting a copolymer of (a1) an unsaturated carboxylic acid and/or unsaturated carboxylic anhydride, (a2) a compound containing at least one hydroxyl group per molecule, and (a3) another unsaturated compound, with at least one isocyanate compound selected from 1,1-(bis-acryloyloxymethyl)ethyl isocyanate, 1,1-(bis-acryloyloxymethyl)ethyl isocyanate, 1,1-(bis-acryloyloxypropyl)ethyl isocyanate, 1,1-(bis-methacryloyloxymethyl)ethyl isocyanate, 1,1-(bis-methacryloyloxyethyl)ethyl isocyanate, and 1,1-(bis-methacryloyloxypropyl)ethyl isocyanate.

    • PURPOSE: An alpha-methylstyrene copolymer is provided to manufactur the copolymer by bulk bpolymerization and to ensure high alpha-methylstyrene content and heat resistance. CONSTITUTION: An alpha-methylstyrene copomymr contains 70-90 weight% of alpha-methylstyrene, 9-29 weight% of vinylcyan compounds, and 1-10 weight% of N-substituted malemide compounds. The vinylcyan compounds contain one or more selected from the group consisting of acrylonitrile, methacrylonitrile, and ethacrylonitrile. A method for manufacturing the alpha-methylstyrene copolymer comprises: a preparing mixture solution containing alpha-methylstyrene, vinyl cyan compounds, N-substitution maleimide compounds, and solvent; and a step of continuously adding the mixture solution.
