A process for treating polymer made by the polymn. of at least one polymerizable monomer in a vapor state reactor comprising removing without substantial pressure letdown solid polymer from said vapor state reactor together with reactor off-gases into a post polymn. zone into which a controlled amount of said monomer is introduced and wherein a controlled amount of essentially adiabatic polymn. occurs and said polymer is melted by heat from said adiabatic polymn. and externally added heat to form efficiently transferable, molten polymer.
