Abstract

<PICT:0866971/IV (a)/1> In a continuous method for the low temperature Friedel-Crafts catalyzed polymerization of an isoolefin in solution in a circulating stream in a reactor with agitation, mass fouling is inhibited by continuously injecting a solution of fresh olefinic feed into the circulating stream at a zone of maximized stream velocity and at an angle within 30 degrees of and including the direction normal to the direction of flow of said stream in the reactor and at an injection velocity equal to at least 80% of the average flow velocity in the reactor. Fig. 2 of the accompanying drawings illustrates part of a suitable apparatus for effecting the method claimed, whereby feed supply from line 48 passes to reservoir 44 and then flows into the reactor at an angle normal to the circulating stream, as shown by the arrows in the Figure.
