Abstract: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, to form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions and can be sprayed at higher solids levels, in ambient air or with heated air applied to just the spray instead of a spray chamber. Novel catalyst supports can be produced having a beneficial morphology such as for olefin catalysis. Drier water-borne coatings can be applied to substrates by using compressed fluids to spray water-borne coating compositions having conventional water levels, thereby reducing runs and sags and shortening dry times.

Abstract: A process for the production of an in situ particulate polyethylene blend comprising contacting a magnesium/titanium based catalyst system including a particulate precursor with one or more alpha-olefins in each of two reactors connected in series, in the gas phase, with the provisos that: (a) the particulate precursor has a particle size distribution span of no greater than about 1.5; and (b) a high molecular weight polymer is formed in one reactor and a low molecular weight polymer is formed in one other reactor wherein the ratio of molecular weights of the high molecular weight polymer to low molecular weight polymer in the final product is at least about 8:1.

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.
