A method for continuously preparing a heat resistant α-methylstyrene-acrylonitrile copolymer by bulk polymerization, comprising the steps of:a) Continuously charging a mixture of monomers including following materials into a continuous polymerization system with two or more stirred-vessel reactors connected in series: i) 60 to 75% by weight of ¥á-methylstyrene;ii) 25 to 40% by weight of acrylonitrile; iii) 5 to 15% by weight of a solvent; and iv) 0.05 to 0.3% by weight of a mixed initiator of an organic peroxide with a multifunctional group and an organic peroxide with a monofunctional group;b) Continuously polymerizing the monomer mixture charged at step a) starting from the first reactor to convert 50 to 70% by weight of total charged monomers into a polymer; andc) transferring reacted liquid containing the polymer from step b) to an evaporator, and then separating the polymer by evaporating unreacted monomers and solvents.Heat resistant α-methylstyrene-acrylonitrile copolymer resins prepared by the method of the present invention are superior in terms of conversion rate, heat resistance and heat stability. Heat resistant ABS resins which contain this copolymer resins exhibit excellent impact strength and processability and low heat discoloration.
