    Abstract: This invention pertains to novel copolyesters consisting essentially of units (I), (II), (III) and (IV), and blends of these polymers and articles made from both. Units (I), (II), (III), and (IV) are present in specified proportions as defined in the description of the invention. The instant copolyesters display orientation in the molten state, good fiber ratings and high strength. Advantageously, the polymers of the present invention display a significant improvement in viscosity and moldability of the neat polymer. The polymers have excellent mechanical and surface properties including blister resistance, strength, toughness, and ability to vapor phase solder, and form strong fibers while still maintaining a high heat distortion temperature. They have melting points in the range of from about 250 to about 360 DEG C and are melt-processible. Advantageously, these compositions filled with about 30 weight percent of glass fibers display heat distortion temperatures of up to 240 DEG C, when measured under a load of 264 psi. The polymers may be blended to tailor properties. These polymers and blends may be used advantageously in producing fibers and in electrical equipment, electronic components and other end uses requiring moderately high temperatures.

    Abstract: Described herein are immiscible poly(aryl ether sulfone) blends possessing improved flow properties. The novel compositions contain (a) from about 80 to about 99 percent by weight of a poly(aryl ether sulfone) having a second order glass transition temperature (Tg) higher than about 240°C, and (b) from about 1 to about 20 percent by weight of a second poly(aryl ether sulfone) having a Tg lower than about 225°C. The compositions described herein retain the very attractive characteristics of their constituents, and display excellent mechanical properties and heat resistance.

    Abstract: A method for converting at least one feedstock alkane containing from 1 to 3 carbon atoms to higher molecular weight hydrocarbons, comprising: (a) contacting the feedstock alkane containing from 1 to 3 carbon atoms with an oxygen-containing gas in a reactor in the presence of an oxidative coupling catalyst at a temperature in the range of from about 600 C to about 1000 C, to thereby produce a gaseous mixture comprising any remaining unreacted feedstock alkane and oxygen and saturated and unsaturated aliphatic hydrocarbon products having higher molecular weights than the feedstock alkane from which they were formed; and (b) contacting the resulting gaseous mixture with an oligomerization catalyst under aromatization conditions to thereby produce a gaseous mixture comprising any remaining unreacted feed stock alkane and oxygen of an aromatic product and a saturated aliphatic hydrocarbon product having a higher molecular weight than the feedstock alkane from which it was produced.

    Abstract: A method of producing hydrocarbons from a subterranean formation comprising the steps of: forming a well having a horizontal section located between the midpoint and the bottom of the formation and having a raised end; and continuously injecting a fluid through said raised end to induce hydrocarbons to flow towards the horizontal section in response to gravity drainage while continuously producing hydrocarbons through the horizontal section of the well-bore, so that the injection of fluids occurs simultaneously with the production of hydrocarbons.
