Abstract

Elastomeric copolymers of ethylene, a C3-10 alpha-alkene, and on unconjugated alkadiene or prepd. continuously by (a) supplying ethylene, the C3-10 alpha-alkene and the unconjugated alkadiene, and a catalyst consisting of a transition metal component and an organoalumium cpd. of formula RmAlXn (where R is alkyl, alkaryl, aralkyl or cycloalkyl; m is 1-3; X is halogen; and m is 1-3) to a first stirred reactor, (b) polymerising a part of the monomers in the first reactor at -50 to 150 degrees C and 0-70 atm. to form a soln. of the polymer, (c) supplying this soln. to a second stirred reactor, (c) introducing into the second reactor ethylene, C3-10 alpha-alkene, unconjugated alkadiene, and/or transition metal catalyst component, and/or the organoaluminium cpd. (d) polymerising monomers under practically the same conditions as in the first reactor, (e) discharging the contents of the second reactor, and completing the polymn of the discharged material, and (f) recovering the copolymer. Gives copolymers with a controlled wide mol. wt. distribution, and a composition distribution controlled within narrow limits, thus enabling the physical properties of the copolymer to be controlled.
