Abstract: A film of poly(trimethylene arylate) and a polystyrene wherein the polystyrene concentration is in the range of 0.5 to 40 weight %. Poly(trimethylene terephthalate) and polystyrene are particularly useful. Also, disclosed are processes for preparing the film.

Abstract: A composition of poly(trimethylene arylate), especially poly(trimethylene terephthalate), and polystyrene that is useful in the production of shaped articles such as fibers, films, and molded structures. The invention is useful as a masterbatch, also known as a concentrate, composition for combining with a PTT diluent in the economical production of fiber spinning compositions.

Abstract: A concentrate of poly(trimethylene arylate), particularly poly(trimethylene terephthalate) and polystyrene containing 15 to 40 wt % polystyrene is employed in the production of shaped articles such as films, pellets, and fibers. In one embodiment the concentrate is melt mixed with a polymeric diluent comprising a poly(trimethylene arylate) to form a spin blend comprising 0.5 to 1.5 wt % polystyrene, and the spin blend is extruded through a spinneret comprising a plurality of identical orficies, producing a plurality of filaments.

Abstract: The present invention relates to a composition being poly(trimethylene terephthalate) and at least one blend polymer. The invention further includes a process of producing reduced-whitening in articles made from the poly(trimethylene terephthalate) and at least one blend polymer.

Abstract: The present invention relates to a process for making a non-whitening poly(trimethylene terephthalate)-based polymer, wherein the polymer is melt polymerized 1,3-propanediol and a terephthalate component in the presence of a co-monomer, wherein the poly(trimethylene terephthalate)-based polymer comprises a PTT cyclic dimer level below 2 wt. %.

Abstract: The electromagnetic valve actuator of the preferred embodiments include a valve head that moves between an open position, a middle position, and a closed position; a plunger coupled to the valve head; and a housing defining a cavity that surrounds the plunger and contains a fluid. The cavity cooperates with the plunger and the fluid to provide increasing resistance as the valve head moves from the middle position to the closed position. Because of the increased resistance, the valve head softly seats against a valve seat, which minimizes noise, vibration, and harshness within the vehicle.

Abstract: New compositions have been discovered which are useful as slurry concentrates to carry solid particles along in a fluid. A non-limiting example would be to carry proppants in a concentrate to a completion fluid being pumped downhole in a hydrocarbon recovery operation. The composition employs both a trivalent salt, such as aluminum chlorohydrate, as a viscosifying agent, and a surfactant. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant in that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately. The viscoelasticity of the concentrate may be easily broken by dilution; other mechanisms are also anticipated.
