Abstract: Sticky polymers are produced at polymerisation temps. above the softening pt. of the polymers in a fluidised bed of a supported catalyst and an inert particulate material. The process is improved by the use, as catalyst support, of a silica having average particle size 60-200 micron with a wt. fraction of no more than 30% smaller than 44 microns. Also claimed is a process as above for producing ethylene-propylene-ethylidene norbornene terpolymer, the silica support having avge. particle size 70-140 microns with a wt. fraction of no more than 20% smaller than 44 microns. Pref. the inert particulate material is pref. from C black, silica, or clay esp. C black having prim. particle size 10-100 nm, average aggregate size 0.1-10 microns, specific surface area 30-1500 m2/g, and dibutylphthalate absorption 80-350 cm3/100g. The silica support pref. has average pore dia. greater than 100 Angstrom, surface area greater than 200 m2/g, and average pore vol. 1.4-2.0 ml/g. The inert particulate material is pref. introduced at a point above the fluidised bed.

Abstract: A process for reducing the amount of hexane extractables present in ethylene copolymer resins produced by gas phase polymerization in the presence of a catalyst having a least one titanium compound, at least one magnesium compound, at least one electron donor compound, at least one activator compound and at least one silica support material, by utilizing a silica support material having a particle size having an average value of 15-25 microns with no more than 5% of the particles being greater than 50 microns.

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.
