ABSTRACT:
Continuous bulk polymerization of thermoplastic resins is carried out by using a horizontal continuous polymerizer comprising a cylindrical body, one or more shafts having the stirring elements and disposed in said body, a material inlet provided at an end of said body in its longitudinal direction, and a material drawing means and an outlet provided at the other end of said body. A monomer is evaporated from a polymerization solution while controlling the pressure in said polymerizer at a predetermined level and, concurrently with this, a monomer is directly sprayed to the free surface of the polymerization solution in the polymerizer from several locations of said polymerizer in its longitudinal direction, whereby to eliminate the heat of polymerization reaction and the heat of stirring to allow progress of the polymerization reaction under a predetermined temperature condition.
