Abstract
A method for the copolymerization of ethylene and a Colefin in a loop reactor and polymers formed therefrom are described herein. The method generally includes introducing an ethylene monomer, a Colefin and a diluent carrier liquid into a loop reactor. A catalyst system can be supplied to said loop reactor. The diluent liquid, ethylene monomer, and Colefin can be circulated through said loop reactor, while copolymerizing said ethylene and Colefin in the presence of said catalyst system to produce a slurry. The slurry can be diverted into a settling leg, and sequentially discharged therefrom and withdrawn from said loop reactor. An ethylene monomer co-feed can be introduced into said loop reactor at spaced locations downstream of the ethylene and diluent. The ethylene co-feed can be introduced in an amount effective to reduce the variation in the ratio of ethylene and Colefin.
