Abstract
The present invention relates to a method for producing a diene-based graft copolymer resin, and a diene-based graft copolymer resin produced therefrom, the method including: mixing an aromatic vinyl-based monomer, a diene-based rubber polymer, and a polymerization initiator to prepare a first reactant; mixing a vinyl cyan-based monomer and an antioxidant to prepare a second reactant; adding and polymerizing the first reactant and the second reactant into a polymerization reactor to prepare a polymer; and removing unreacted monomers in a devolatilization tank.
Claims9
A method for producing a diene-based graft copolymer resin, the method comprising:
- mixing an aromatic vinyl-based monomer, a diene-based rubber polymer, and a polymerization initiator to prepare a first reactant;
- mixing a vinyl cyan-based monomer and an antioxidant to prepare a second reactant;
- adding and polymerizing the first reactant and the second reactant into a polymerization reactor to prepare a polymer;
- and
- removing unreacted monomers in a devolatilization tank,
- wherein with respect to 100 parts by weight of the first reactant, the aromatic vinyl-based monomer is contained in a content of 60-80 parts by weight, the diene-based rubber polymer is contained in a content of 5-20 parts by weight, and the polymerization initiator is contained in a content of 0.01-0.1 parts by weight,
- wherein the antioxidant is contained in a content of 0.1-1.0 parts by weight with respect to 100 parts by weight of the vinyl cyan-based monomer,
- wherein the antioxidant is at least one selected from the group consisting of a hindered phenol-based antioxidant and a phosphorus-based antioxidant.
