摘要：PROBLEM TO BE SOLVED: To provide anα-methylstyrene-based copolymer giving a molded article excellent in heat resistance and thermal stability by being added to a thermoplastic resin. SOLUTION: Thisα-methylstyrene-based copolymer comprises 68-75 mass%α-methylstyrene unit, 3-12 mass% styrene unit and 20-26 mass% vinyl cyanide compound unit, provided that the total of respective units is set as 100 mass%, in which a catenation block content consisting of anα-methylstyrene unit, anα-methylstyrene unit and a styrene unit is 2-12 mol%, when the total of catenation blocks formed by optional three consecutive monomer units containing at least one of the above monomer units is set as 100 mol%.
