Abstract: The subject invention provides a composition having excellent extrusion characteristics comprising a difficulty-melt-processible polymer and 0.002-0.5 wt. % of one or more fluoropolymer process aids wherein the fluoropolymer has a fluorine to carbon ratio of at least 1:2, is capable of forming a die-coating film under the prevailing conditions of extrusion temperature and pressure, and contains an effective amount of polar functional polymer chain end groups, -W, wherein -W is selected from -COF, -SO2F, -SO3M, -OSO3M, -COOR, and -COOM, wherein R is C1-3 alkyl and M is hydrogen, a metal cation, preferably an alkali or alkaline earth metal cation, or a quaternary ammonium cation.

Abstract: A solution for evaluating the pupillary responses of a patient is disclosed. The solution includes exposing one eye of a patient to flashes having varying patterns and concurrently recording the pupillary responses of both eyes of the patient to the flash. At least some of the patterns can be configured to stimulate/not stimulate the macula region of the patient's eye. The solution also can include reducing one or more non-visual stimuli experienced by the patient while the pupillary responses are being induced and recorded.
