A method of making a pyranine monomer composition comprises the step of reacting pyranine with a functionalizing agent that functionalizes the pyranine molecule with a polymerizable functional group to provide a composition of functionalized pyranine monomers, said functionalization reaction taking place in an aqueous reaction medium, and in the presence of a molar excess of said functionalizing agent, such that the functionalization reaction product is a monomer composition substantially free of unfunctionalized pyranine compound. The pyranine monomer compositions made by the method can be used to make fluorescent tagged water soluble polymer compositions that advantageously are substantially free of unpolymerized pyranine. The fluorescent tagged water soluble polymer compositions can be used in a method of inhibiting scale in industrial water systems.

The application relates to compositions comprising di-fatty-alkyl or -alkenyl polyalkylamines of the general formula (I) or (II), to a process for their preparation which involves a cyanoethylation step and a hydrogenation step, and their use as demulsifiers for oil-in-water emulsions, corrosion inhibitor, fuel additive, anti-scaling agent, asphalt additive, enhanced oil recovery agent for oil-wells, cutting-oil additive, and anti-static agent. The product show good performance combined with a favourable viscosity profile.

A catalyst component, adapted for use in the polymerization and copolymerization of ethylene, is formed by reaction of an organomagnesium compound with a metal oxide support to form a supported organomagnesium composition, reaction of the supported organomagnesium composition and a tetraalkyl silicate, contact of the resulting product with a chlorinating reagent, and treatment of the product from the previous step with liquid titanium halide.

A substantially pure, chemically distinct halomagnesium alkoxide compound is formed by reaction of a dihydrocarbylmagnesium compound with a compound which will replace an hydrocarbyl functionality thereon with an hydrocarbyloxy functionality and thereafter reacting the resulting product with a compound which replaces the other hydrocarbyl functionality with a halogen functionality, such as chlorine. The .sup.13 C nuclear magnetic resonance spectrum of the product exhibits no more than one strong, narrow absorption peak for each chemically inequivalent carbon atom in the hydrocarbyloxy ligand of the compound.

Fibers of an alternating carbon monoxide-ethylene polymer having a molecular weight of at least 100,000 g/mole and a birefringence of at least 650.times.10.sup.-4 can be formed by first extruding a solution of the polymer in a mixed solvent system comprising an aromatic alcohol which is free of alkyl substituents on the aromatic nucleus and another solvent which is a liquid and is other than an aromatic alcohol. The extrusion into the solvent is at an extrusion rate of at least 1 m/min and forms a solvent-containing article which is then cooled or coagulated in a non-solvent for the polymer. The solvent is removed by extraction with a non-solvent for the polymer which is soluble in the mixture of solvents and the resulting article is drawn at a temperature of at least 180.degree. C.

Hydrocarbon-soluble complexes of magnesium haloalkoxides and alcohols (X.sub.n Mg(OR).sub.2-n.mR'OH pR'OH) are prepared in a non-Grignard reaction involving combination of sources of magnesium, halide, and alkoxide in the presence of an excess of the alcohol for the desired alkoxy group and an amount of lower alkyl alcohol to effect the desired solubilization of the complex.
