Abstract
Disclosed is a process for the production of ABS resins comprising the steps of (a) imbibing a stabilized latex of a rubbery polymer with styrene in an amount of about 1.75 to 15 parts by weight per 100 parts of dry latex and with acrylonitrile in an amount of about 5 to 15 parts by weight per 100 parts of dry latex; (b) introducing the imbibed latex into a polymerization vessel; (c) introducing into the polymerization vessel a mixture of styrene, acrylonitrile and a free radical initiator; (d) introducing a polymerization activator into the polymerization vessel; (e) polymerizing the styrene and acrylonitrile in the polymerization vessel in the presence of the latex, whereby an ABS graft copolymer is produced; and (f) withdrawing the ABS polymer from the polymerization vessel.
