摘要:
The present invention discloses an emulsion polymerization process that comprises: (1) preparing an aqueous polymerization medium which is comprised of (a) at least one monomer, (b) a polymerization control agent, and an emulsifier, wherein the emulsifier is prepared in-situ within the aqueous polymerization medium; and (2) initiating polymerization of said monomer within the aqueous polymerization medium. The subject invention more specifically reveals an emulsion polymerization process that comprises: (1) preparing a monomer solution which is comprised of (a) at least one monomer, (b) a conjugate acid of a surfactant with a pKa of less than 14, and (c) a controlled free radical polymerization agent; (2) preparing an aqueous medium which is comprised of (a) water, and (b) a conjugate base of a weak acid wherein the pKb of the base is less than 14; and (3) mixing the monomer solution with the aqueous medium under conditions that result in the in-situ formation of an emulsifier, and (4) initiating free radical polymerization.

The present invention provides shared communication medium capability to the plethora of computer devices, like the PCCAs, that normally are able to communicate with other devices via dedicated point-to-point links, e.g., via the practically universal RS-232 ports. It allows the sharing of the communication medium in a dynamic fashion depending on the instantaneous traffic demands by the various communicating devices. It further allows the emulation of point-to-point links over the shared communications medium in such a way that applications running on a PCCA use the shared medium transparently. Thus, this invention enables applications designed to operate over a point-to-point connection to operate over the shared medium without any modifications of the applications or the point-to-point devices. It enables the shared medium communications and dynamic communication resource allocation by using a device's I/O ports designed for point-to-point communications with dedicated communication resource allocation.

Electrochromic device and method. In one disclosed embodiment, an electrochromic coating is applied to a light transmissive substrate, and a first control voltage is generated in accordance with the amount of light impinging upon the substrate. That control voltage is applied to the electrochromic coating to decrease the transmittance of the substrate as the light increases. Ambient light conditions are monitored to provide a second control voltage which is applied to the electrochromic coating to decrease the transmittance of the substrate when the ambient light falls below a predetermined level, e.g. at night. In other disclosed embodiments, the electrochromic coating is applied to the lenses of a pair of glasses and to a lamp shade, with photovoltaic cells for controlling the transmittance of the coating in accordance with the amount of impinging light.
