ABSTRACT:
A first reactor is used to graft polystyrene to a rubber-like polymer. A second reactor is used to obtain a mixture of styrene and polystyrene. The effluent from both the first and the second reactors are fed into a quiescent reaction zone where phase inversion occurs. The phase inverted material is fed into post inversion reactors to substantially complete the polymerization of the styrene monomer, and any unreacted styrene monomer is driven off to form the improved high-impact polystyrene.
