Abstract[English]
A solution phase polymerization process utilizes multiple reactors connected in series to make a polyethylene composition. Two different single site catalysts are fed to a first upstream reactor and a Ziegler-Natta catalyst is fed to a second downstream reactor. Optionally, a third polymerization reactor, also connected in series is employed. The single site catalysts fed to the first reactor include a metallocene catalyst and a phosphinimine catalyst. The solution phase polymerization process affords a polyethylene composition comprising a first polyethylene, a second polyethylene, and optionally a third polyethylene.[French]
Un procédé de polymérisation en phase solution utilise de multiples réacteurs connectés en série pour fabriquer une composition de polyéthylène. Deux catalyseurs à site unique différents sont introduits dans un premier réacteur amont et un phosphinimine est introduit dans un deuxième réacteur aval. Éventuellement, un troisième réacteur de polymérisation, également connecté en série, est utilisé. Les catalyseurs à site unique introduits dans le premier réacteur comprennent un catalyseur métallocène et un catalyseur phosphinimine. Le procédé de polymérisation en phase solution permet d'obtenir une composition de polyéthylène comprenant un premier polyéthylène, un deuxième polyéthylène et éventuellement un troisième polyéthylène.
