which are known to form stable complexes with any of the catalyst components particularly the lewis acid or the vanadium compound are undesirable and should be avoided the interpolymers of this invention may be prepared in batch semi continuous of fully continuous processes in which homogeneous soluion slurry or cement suspension systems are utilized in a typical batch process a reactor fitted with efficient agitation means and means for heat exchange is purged of air by displacement with oxygen free nitrogen argon or low boiling saturated hydrocarbon vapors such as methane ethane or propane and charged with a solvent or mixture of solvents in all process versions monomers and catalyst components pre diluted with solvent if desired may be introduced into the stirred reactor either simultaneously or sequentially at a rate consistent with the means used for heat exchange to maintain the desired temperature range pressure on the reactor is maintained at a level sufficient to keep the reactants in the liquid phase the catalyst components may be mixed in line in the absence of monomers before they are added to the reactor or they may be added directly to the reactor in the presence of unreacted monomers temperatures at which polymerization may be conducted may range from 100 u00b0 c to 100 u00b0 c preferred are temperatures in the range of 80 u00b0 c to 50 u00b0 c most preferred are temperatures in the range of 40 u00b0 c to 40.
