PROCESS FOR PREPARING ABS LATEX FOR MBS IMPACT MODIFIERS

摘要

The present invention relates to a manufacturing method capable of producing SB latex for MBS resin excellent in impact resistance and transparency in a short time, more specifically 150 to 250 parts by weight of ion-exchanged water, 0.01 to 4 parts emulsifier with respect to 100 parts by weight of SB latex solids Polymerization reaction at 30 to 60 ℃ for 3 to 4 hours by reacting the reactants consisting of parts by weight, 93 to 98 parts by weight of monomer, 0.1 to 1 parts by weight of polymerization initiator, 0.1 to 5 parts by weight of reducing agent, crosslinking agent and 0.05 to 2 parts by weight of other additives. First step; And a second step of adding the reducing agent together with ion-exchanged water to the polymerization reaction of the first step to polymerize for 3 to 6 hours, and in the first step, a polymerization initiator / reducing agent in a molar ratio of 2 to 5. The present invention relates to a method for producing SB latex for an MBS impact modifier, which is added and added in a second step so that the molar ratio of the polymerization initiator / reducing agent is adjusted to 0.9 to 1.5.
