forming the rubbric latex of 0.2-1.0μ particle size, of particle formable core-shell form, by continuous inputting 70-99 wt. pts of rubbric forming monomer, 0.1-1 wt. pts of emulsifier, 0.1-5 wt. pts of crosslinking agent, 0.01-2 wt. pts of polymn. initiator and ion-exchange water; graft polymerizing, as continuous in putting of, 30-60 wt. pts of the obtd. rubbric latex, 15-40 wt. pts of monovinyl idene aromatic hydrocarbon, 5-25 wt. pts of unsatd. nitrile, 0.1-5 wt. pts of emulsifier, 0.01-2 wt. pts of initiator and ion-exchange water; removing the unreacted monomer by inputting monovinyliden aromatic hydrocarbon, unsatd. nitrile, etc.
