Abstract
Methods for coagulating a graft polymer latex comprise contacting the latex with sulfurous acid. The methods are particularly suitable for ABS resins and provide products having improved thermal oxidative stability and color stability. When coagulation is effected in the presence of a radical initiator, the residual grafting monomer concentration in the resin product is reduced.
