Abstract: The disclosure relates to crosslinked ion-exchange materials (IEM), related methods of making lEMs, and related articles including IEMs. The IEMs can be formed by providing a reaction solution including a charged vinyl monomer, a polyfunctional vinyl crosslinking monomer, a vinyl polymerization initiator, and water; and then performing vinyl polymerization in the reaction solution to form the IEM as a crosslinked reaction product. The reaction solution contains primarily or only water as a solvent for the vinyl monomers. The resulting crosslinked reaction product has a combination of high ionic-exchange capacity (IEC) values coupled with low water uptake and/or low water mass fraction values, which make it suitable for use in various ion-exchange applications.

Abstract: A painter's tool belt comprising an elongated linear belt member for wrapping around a waist of a user; the belt member provided with a fastener assembly. Mounted on the belt member is a transparent plastic cylindrical open ended caulking gun pouch, a loop member, a hammer loop assembly, a first rectangular transparent plastic pocket with a top opening, a second rectangular transparent plastic cutting tool pocket having a length which is longer than the first rectangular plastic pocket, the second rectangular cutting tool pocket having a top opening positioned above the first rectangular transparent plastic pocket top opening and a transparent plastic paint brush pocket secured to said belt member, the paint brush pocket comprising a flap section and a brush section secured to the flap section, the brush section being formed of a wider upper section and an integral narrower lower section.

Abstract: An optical illumination assembly comprising an array of optical microprisms and microlenses for redirecting light from a light source. Such displays are used in a wide variety of applications such as backlit flat panel displays requiring a directed light source which provides an efficient output of light. The illumination assembly has a light transmitter optically coupled to an input end of array of microprisms through an optional diffuser, and a microlens on the light output end of each microprism. The microprisms have a light input end optically coupled to the light transmitting means and a light output end spaced from the light input end.
