Abstract: An in situ blend formed in the gas phase in two or more reactors connected in series comprising a mixture of two types of particles of polyethylene, (i) one type of particle containing a major proportion of high molecular weight polyethylene and a minor proportion of low molecular weight polyethylene and having a relatively high split ratio and (ii) one type of particle containing a major proportion of low molecular weight polyethylene and a minor proportion of high molecular weight polyethylene and having a relatively low split ratio wherein the average particle size of the blend is at least about 300 microns; the average split ratio of the blend is in the range of about 40:60 to about 60:40; and no more than about 10 percent by weight of the particles in the blend have a split ratio below 90 percent of the average split ratio of the blend.

Abstract: Polymers are produced in a stirred bed or gas fluidised bed polymerisation zone of growing polymer particles by (1) introducing a stream of monomer(s), and opt. inert gas(s) or liq(s)., into the polymerisation zone; (2) continuously or intermittently introducing a catalyst; (3) continuously or intermittently withdrawing polymer; and (4) continuously withdrawing unreacted gases, compressing and cooling the gases while maintaining the temp. in the polymerisation zone below the dew pt. of at least one monomer; with the proviso that if there is only one monomer present in the feed stream, an inert gas is also present.

Abstract: A process for producing sticky polymers at polymerization reaction temperatures in excess of the softening temperature of the sticky polymers in a fluidized bed reactor catalyzed by a transition metal catalyst, which comprises conducting the polymerization reaction above the softening temperatures of the sticky polymers in the presence of about 0.3 to about 80 weight percent, based on the weight of the final product of an inert particulate material having a mean particle size of from about 0.01 to about 10 microns whereby polymer agglomeration of the sticky polymers is maintained at a size suitable for continuously producing the sticky polymers.
