Method for producing rubber modified thermoplastic resins

摘要

Disclosed is a method for producing a rubber modified thermoplastic resin excellent in surface appearance and various properties and high in commercial values which comprises removing an aqueous phase from a two-phase mixture comprising a graft rubber polymer latex (1) obtained by graft polymerization of vinyl monomer on a rubber latex, a thermoplastic resin (2), an organic agent in an amount of 0.1 to 6 times the weight of all the polymers (3) which is capable of dissolving said thermoplastic resin (2) and has a solubility in water of 5% by weight or less at 25 DEG C. and a water soluble agent in an amount of 10% by weight or less of said graft rubber polymer which can coagulate said latex and then removing said organic agent and remaining water from the remaining organic phase by a thermal means.
