| abstract |
Polymer having a polymodal MWD ethylene copolymer are prepared by conducting the polymerization in a substantially mix free reactor using an essentially transfer agent free reaction mixture, the reaction being carried out in a manner such that the propagation of essentially all copolymer chains is initiated simultaneously. In carrying out the process of this invention, the catalyst components are premixed and aged prior to introduction into the reactor. The process is preferably carried out in a tubular reactor using VCl4 and aluminum sesquichloride as the catalyst system. |
