so as to provide suitable reaction conditions for the dimerization oligomerization or polymerization or any combination thereof of the alphaolefin of the monomer feed to give a polyalphaolefin product the reaction pressure generally can be maintained in the range of from below atmospheric upwardly to about 250 psia since the reaction is not significantly pressure dependent it is most economical to operate the reactor at a low pressure preferably from about atmospheric to about 50 psia and most preferably from atmospheric to 25 psia the reaction temperature is to be maintained during the reaction so as to keep the reactants and catalyst in the liquid phase thus generally the reaction temperature range is from about 20 u00b0 f to about 200 u00b0 f preferably the reaction temperature shall be in the range of from about 40 u00b0 f to about 150 u00b0 f and most preferably from 50 u00b0 f to 110 u00b0 f the residence time of the feed within the reaction zone has a small influence on the resultant reaction product as used herein the term u201c residence time u201d is defined as being the ratio of the reactor volume to the volumetric introduction rate of the feeds both the monomer feed and the ionic liquid catalyst feed charged to or introduced into the reaction zone defined by a reactor the residence time is in.
