Abstract: The particle size of as formed polyethylene or ethylene copolymer containing up to about twenty percent of a C.sub.3 to C.sub.8 olefin can be increased by using a high yield, solid catalyst component prepared from (1) a magnesium alkoxide, (2) a titanium (IV) or vanadium (V) chloride, chloroalkoxide or alkoxide, (3) an alkylaluminum compound, and (4) hydrogen chloride. The particle size of as formed polymer can be increased substantially using the hydrogen-chloride-prepared catalyst component, compared to the particle size of polymer made using a similar catalyst component prepared without the use of hydrogen chloride, when either is employed with an alkylaluminum compound promoter in a slurry or vapor phase polymerization process at moderate polymerization temperatures and pressures.

Abstract: An improved plastic composite pipe structure includes an outer corrugated pipe, an inner smooth-walled liner, and joining means including a bell fitting at one end of the liner extending beyond the outer corrugated pipe and a spigot fitting at the other end. The corrugations of the outer pipe at the spigot end are undercut so as to slide over and provide crush resistance to the joint that is formed when the spigot of one composite pipe section is inserted into and engaged with the bell of an adjacent composite pipe section. A seal, for example, an elastomeric gasket, solvent weld, or elastomer-based adhesive is used to provide a leakproof joint. Optionally, an outer pipe cover can be utilized as a component of the composite pipe.

Abstract: A process is disclosed for producing the dimethyl esters of aromatic dicarboxylic acids wherein the acid is esterified with a low molecular weight alcohol, the product is crystallized and separated to isolate a mass of the diester crystals and recover a mother liquor. An improvement in such process resides in the thermal oxidation with molecular oxygen of a mother liquor material to produce a mono methylphthalate from either p-methyl toluate or methyl-4-carboxybenzaldehyde. A portion of the oxidized mother liquor is recycled to the esterification zone wherein the mono methylphthalate can be esterified to the dimethyl ester while another portion of the oxidized mother liquor stream is passed to an evaporation treatment zone, preferably a wiped film evaporator, wherein overhead material is separated from a high boiling bottoms material and recycled to the esterification reaction zone.

Abstract: This invention relates to a novel lubricant oil addition agent which is a phosphosulfurized C.sub.35 to C.sub.160 hydrocarbon modified N-(hydroxy and C.sub.50 - C.sub.160 alkyl-substituted benzyl) alkylene polyamine. Such novel addition agent imparts anti-oxidant and unexpected dispersancy functions to lubricant oils commonly used as crankcase lubricants for internal combustion engines. Such novel addition agent also imparts anti-oxidant and detergency functions to the less viscous oils used to lubricate automatic transmissions and at the same time prevent failure of the rubber seals used therein from deterioration (hardening) by oxidation and distortion softening by undue swelling. The present inventive addition agent unexpectedly provides both detergency and an anti-oxidant functions for lubricant oil which are superior to the related analog addition agent derived from the reaction of one molar proportion of a phosphosulfurized 500 to 2800 (Staudinger) molecular weight hydrocarbon with from 0.

Abstract: Viscous polybutenes of number average molecular weight (M.sub.n) in the range of about 300 to about 3000 have improved reactivity with intramolecular anhydrides of unsaturated aliphatic dicarboxylic acids when reacted in the presence of rather small amounts, i.e., 5 to 200 ppm, of alpha halogen-containing, preferably chlorine or bromine-containing, aliphatic or aromatic carbonyls including acetals as additives. Use of such halogen-containing additives in the addition reaction of polybutene with said unsaturated anhydrides can reduce formation of undesired tarry product resulting from polymerization and/or thermal decomposition of the unsaturated anhydrides.
