    Abstract: An L-shaped mixing head (10) for reaction injection molding apparatus comprises a first chamber (14) wherein a plurality of reactive molding components are impingement mixed under high pressure. A second chamber (16) intersecting with the first chamber quiets the resulting stream of mix product prior to its exiting the mixiing head. The outlet end (18) of the second chamber is defined by the inner surface (40) of a sleeve (42), the material of which has a yield strength less than that of the materials of the mixing head body and the second plunger (32). Most preferably, the sleeve material is also chemically nonreactive with and nonadherent to the reactive molding components to be used therewith, both individually and as mixed.

    Abstract: An electrochromic device (10) incorporating an electrochromic material (13) and a perfluorosulfonic acid polymer ion conducting layer (14) interposed between a working electrode (12) and a counter electrode (15), characterized by the feature that the perfluorosulfonic acid polymer layer (14) comprises a substantially fluorinated backbone which has recurring pendant groups attached thereto represented by the formula -O-(CFR'f)b-(CFRf)a-SO3-, where a=0-3, b=0-3, a+b= at least 1, and Rf and R'f are independently selected from a halogen and a substantially fluorinated alkyl group having one or more carbon atoms. One example of such a polymer is the copolymer of tetrafluoroethylene and 1,1,2,2-tetrafluoro-2-((trifluoroethenyl)oxy)ethane sulfonic acid having an equivalent weight of about 800. The primary benefit of the present invention is that the electrochromic device darkens sufficiently to be useful when the device is operated at high temperature such as can be encountered in an automobile electrochromic sun roof on a sunny day in a hot climate.
