Procedure
To a metal bottle, ion exchanged water in 180 parts, concentration 10 wt % of sodium dodecyl benzene sulfonate aqueous solution in 25 parts, acrylonitrile in 37 parts, mono-n-butyl maleate in 6 parts, and t-dodecyl mercaptan (molecular weight adjuster) in 0.75 part were charged in that order. The inside air was replaced with nitrogen three times, then 1,3-butadiene in 57 parts was charged. The metal bottle was held at 5° C., cumen hydroperoxide (polymerization initiator) in 0.1 part was charged, then the metal bottle was rotated while performing a polymerization reaction for 16 hours. After that, a concentration 10 wt % of hydroquinone aqueous solution (polymerization anticatalyst) in 0.1 part was added to stop the polymerization reaction, then a water temperature 60° C. rotary evaporator was used to remove the residual monomers and thereby obtain a latex of acrylonitrile-butadiene-mono-n-butyl maleate copolymer rubber (solid concentration of about 30 wt %).
