ABSTRACT Apparatus for the vapor phase polymerization of at least one polymer- izable monomer comprising: (a) a horizontal, stirred reactor of substantially circular cross section containing a centrally-located drive shaft extending longitudinally through said reactor to which are attached a plurality of adjacently located paddles, which paddles cause essentially no forward or backward movement of the particulate matter contained in said reactor and extend transversely within and to a short distance from the internal surfaces of said reactor, said reactor being divided into two or more individually polymerization-temperature controllable polymerization sections by one or more barriers constructed to allow free gas mixing within said reactor and control particulate movement between said sections:(b) driving means for said drive shaft; (c) one or more outlets for removal of reactor off-gases situated along the topward part of said reactor; (d) one or more vapor recycle inlets situated along the bottomward portion of said reactor for the introduction of said at least one monomer; (e) one or more catalyst addi- tion inlets situated along said reactor; (f) a plurality of quench liquid inlets situated along the topward part of said reactor whereby quench liquid may be introduced into said polymerization sections of said reactor; and (g) a particulate matter take-off at one end of said reactor.
