Abstract: Flame retardant flexible polyurethane foam compositions, methods of flame retarding flexible polyurethane foam compositions, articles made therefrom and flame retardants that comprise blends of (alkyl substituted) triaryl phosphate ester and phosphorus-containing flame retardant having at least about 5 wt. % phosphorus additives. The combined weight of the (alkyl substituted) triaryl phosphate ester and the phosphorus-containing flame retardant comprises about 5 to about 40% by weight of the flexible polyurethane foam compositions or reaction mixtures. The ratio of the (alkyl substituted) triaryl phosphate ester to the phosphorus-containing flame retardant is from about 95:5 to about 50:50 percent by weight.

Abstract: A single-step process is disclosed for the ring alkylation of at least one N-alkyl-N?-phenyl-phenylenediamine with at least one olefin wherein the process comprises heating a mixture of the N-alkyl-N?-phenyl-phenylenediamine(s) and olefin(s) in the presence of a catalytic amount of at least one alkyl aluminum halide at a temperature of from about 50 to about 350° C. in a sealed vessel for from about one to about 30 hours.

Abstract: A polymerization catalyst system and process, which utilizes a Group 14 and Group 16 containing non-crystalline compound to solubilize or emulsify polymerization catalyst components, is disclosed.

Abstract: The present invention relates to the use of at least one solid compound that when used with a polymerization catalyst in a polymerization process results in a phase change of the solid compound to a liquid that renders the polymerization catalyst substantially or completely inactive.

Abstract: Methods of calcining non-zeolitic molecular sieve catalyst to remove most, if not nearly all, of halogen contained in the catalyst. One method includes heating the catalyst in a low moisture environment, followed by contacting the heated catalyst with air and/or steam. Another method includes steam-treating the catalyst at a temperature from 400° C. to 1000° C. The calcination methods provides a catalyst that contains from about 10 ppmw to about 600 ppmw chlorine, preferably 10 ppmw to about 200 ppmw chlorine, more preferably 10 ppmw to about 80 ppmw chlorine.

Abstract: This invention relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins and a first catalyst and an activator into the reactor and allowing the olefins to polymerize, (b) obtaining a polyolefin, (c) introducing a second catalyst and an optional activator into the first catalyst/activator composition and thereafter introducing the combination into the reactor and allowing the olefins to polymerize. This invention further relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins, a first catalyst and an activator, and a second catalyst and an optional activator into the reactor, wherein the all the catalysts and activators are combined together prior to being introduced into the reactor.

Abstract: This description addresses a process for the preparation of polyolefins from one or more olefinic monomers comprising combining said olefins under olefin polymerization conditions with i) a transition metal organometallic catalyst compound, ii) a Lewis acid-base complex where the Lewis acid group is an aluminum or boron compound having at least one halogenated aryl ligand and the Lewis base group is an amine or ether compound, said combining being conducted in the presence of a tri-n-alkyl aluminum or gallium compound.
