Procedure
The addition of the monomer-chain transfer solution prepared by adding 1.65 parts of Carlisle Q-43 to 66.0 parts acrylonitrile and 22.0 parts styrene was begun immediately, and pumping was conducted lineraly over a period of four hours. The reaction was continued for an additional 45 minutes and was terminated by the addition of 0.01 part Naugard BHT. The temperature was held at 70°C while the unreacted monomers were removed under a vacuum of 20 inches Hg. The total solids content of the resulting latex was 29.5%. The latex was coagulated in 11/2 volumes of water, heated to 88°-90°C and containing 3 grams Al2 (SO4)3.18H2O per hundred grams of resin solids.
