Abstract:
Improved catalysts are disclosed for producing highly crystalline alpha-olefin polymers and highly crystalline copolymers of an alpha-olefin with ethylene or other olefins. Such catalysts can reduce the amount of coproduced amorphous polymer formed without substantial adverse effect on polymerization yield. These novel catalysts involve improving an alkylaluminum component-titanium chloride catalyst by using such catalyst in combination with effective amounts of sulfur dioxide and certain amines. Such catalyst compositions are useful in slurry polymerization, bulk polymerization and, particularly, vapor phase polymerization.

Abstract:
Block copolymers containing styrene, alpha-methylstyrene, 3,4-dimethyl-alpha-methylstyrene and lauryl methacrylate are useful as viscosity index improvers in lubricating oils.
Catalyst And Process For The Polymerization Of Alpha-Olefins
Novel catalysts and processes are disclosed for producing highly crystalline polypropylene and highly crystalline copolymers of propylene with ethylene or propylene with other alpha-olefins. Such catalysts can reduce the amount of low-molecular-weight and, particularly, amorphous polymers formed without serious effect on the polymerization yield. These novel catalysts and processes involve improving an alkylaluminum compound-titanium chloride catalyst by using in combination small amounts of hydrogen sulfide and a sterically hindered, lower alkyl substituted, cyclic, tertiary amine, a sterically hindered, lower alkyl substituted, cyclic, amine oxide, or a trihydrocarbylphosphite. Such catalyst systems are useful in slurry polymerization, bulk polymerization and techniques in which polymerization is accomplished utilizing monomer substantially in the vapor phase.

Abstract:
Process for modifying a titanium trichloride-organoaluminum alpha-olefin polymerization catalyst to reduce production of alkane soluble products during polymerization of alpha-olefins in the presence of such catalyst without substantial decreases in catalyst activity, said process comprising combining in an inert diluent and in the substantial absence of catalyst poisons, components comprising an alkylaluminum component, a titanium trichloride, hydrogen sulfide or a bis-(trialkyltin)sulfide, a tertiary amine, and an aromatic dicarbonyl compound selected from the group consisting of dialdehydes and lower alkyl diesters of ortho-, para- and meta-phthalic acids. Polyalpha-olefins containing reduced levels of low molecular weight and amorphous components are produced by contacting the catalysts with at least one polymerizable alpha-olefin under polymerizing conditions.

International Classification:
C08F 242 C08F 612
US Classification:
526 84
Abstract:
A method is disclosed for terminating a polymerization reaction of reactive olefins and a Lewis acid catalyst wherein the reaction is killed almost instantaneously to prevent an explosion. The material added to terminate the reaction is non-toxic and is easily removable in further processing.

Abstract:
Novel catalysts and processes are disclosed for producing highly crystalline polypropylene and highly crystalline copolymers of propylene with ethylene or propylene with other alpha-olefins. Such catalysts can reduce the amount of low-molecular-weight and, particularly, amorphous polymers formed without serious effect on the polymerization yield. These novel catalysts and processes involve improving an alkyl-aluminum compound-titanium chloride catalyst by using in combination small amounts of sulfur dioxide and isobutylvinyl ether. Such catalyst systems are useful in slurry polymerization, bulk polymerization and techniques in which polymerization is accomplished utilizing monomer substantially in the vapor phase.
Back in Ottawa, insiders agree with Andrew that we should just chill about bubbles, actual or impending. Ottawas housing market is steady Eddy, says John Rogan of Royal Lepage Performance Realty. He points to a stable work force and high incomes as helping keep the Ottawa market in balance.

The 61-year-old collaborated with John Rogan and Brian Yorkey over the last three years to write the music. It is a homecoming story set against the backdrop of the decline of the shipbuilding industry in Newcastle during the 80s, the Times reports. Many of the songs were used in the musical, but
"Very rigorous tiering of pay has happened in the past, but it's starting to look like it will be more acute going forward," said John Rogan, head of global banking and markets at the recruiting firm Russell Reynolds.
