Abstract: A process for producing an ethylene-based polymer comprises polymerizing, by the presence of at least one free-radical initiator and using a high pressure tubular polymerization process, a reaction mixture containing ethylene and at least one CTA system comprising one or more CTA components to produce the ethylene-based polymer. The free-radical initiator is dissolved in a solvent comprising a saturated hydrocarbon to form an initiator solution which is added to the polymerization using an initiator feed line to an initiator injection pump. At least 50 wt % of the solvent has i) a dry point of less than or equal to 160° C. and ii) an initial boiling point of greater than or equal to 100° C. The polymerization process has a ratio of inlet pressure to first peak temperature of less than or equal to 9 Bar/° C.

Abstract: Reinforced composite pipes and methods for making the same, generally employ at least one polymeric reinforcement phase, typically provided as an intermediate form. The intermediate form is typically applied over a core pipe, and may be consolidated. An optional jacket may be employed.

Abstract: The instant invention is a multilayer structure, and a process for making a multilayer structure. The multilayer structure includes (a) a first layer comprising one or more primary layers, wherein the first layer has a thickness in the range of less than 1 cm,—(b) a second layer comprising one or more secondary layers derived from one or more polyolefin dispersions, wherein the one or more secondary layers have a thickness in the range of less than 15 ?m; and (c) a third layer comprising one or more tertiary layers having a thickness in the range of less than 150 ?m. The second layer is disposed therebetween the first layer and the third layer.

Abstract: A learning and assessment aid (10) for helping visually impaired individuals develop desirable ambulatory motion habits. The learning aid includes a housing (14) designed to be attached to an article of clothing worn by the individual. Internal to the housing is an inertial transducer (16) that monitors the rotation of the housing and the individual. The individual enters commands to the learning aid through a keypad (20) in response to audible instructions generated over a speaker (22). To foster desirable turning motions, the learning aid informs of the extent to which the individual turns. To foster straight-line walking, the learning aid generates a message over the speaker whenever the individual rotates more than a pre-set individual-entered maximum veer.
