    • Polymers of anionically polymerized monomers such as mono-olefins, conjugated dienes, vinyl substituted aromatics, vinyl substituted pyridine, vinyl substituted quinolines, various aldehydes, various epoxides, various oxetanes, various oxygen-containing compounds, and the like are produced and end capped with a polyisocyanate or polyisothiocyanate having the formula R--N.dbd.C.dbd.X).sub.n wherein R is a hydrocarbon, n is 2 or 3, and X is oxygen or sulfur. Such end capped polymers, of course, contain one reacted or connected isocyanate or isothiocyanate group and at least one free isocyanate or isothiocyanate end group, which free end group(s) reacts with an amide to give an imide end group. The imide terminated polymer is then hydrolyzed to form a stable amine terminated polymer. The reaction of the amide compound with the isocyanate(s) or isothiocyanate(s), followed by hydrolysis, results in the replacement of the free isocyanate or isothiocyanate end group(s) with an amine group(s). Thus, the amine terminated polymer contains the polymer connected to an isocyanate or isothiocyanate group (now an amide group or a thioamide group), which in turn is attached to the hydrocarbon portion, that is, the "R" portion of the polyisocyanate, which in turn is connected to the formed amine group. The amine terminated polymers may be stored extended periods of time and then reacted with various polymers, prepolymers, monomers, or various combinations thereof to form various block or graft copolymers. That is, the amine terminated polymer may be subsequently reacted with any amine reactive compound such as diepoxy monomers or an epoxy prepolymer in the presence of known epoxy catalysts to give a blocked epoxy copolymer. Similarly, the amine terminated polymer may be reacted with urea prepolymers or urea-forming monomers to yield a block urea copolymer. Reaction of the amine terminated polymer with urethane polymers, urethane prepolymers, or urethane-forming momomers will yield a urethane block copolymer. Reaction of the amine terminated polymer with urethane-urea prepolymers of urethane-urea forming monomers will yield a urethane-urea block copolymer. Similarly, various dianhydride and diamine monomers may be utilized to form an imide block copolymer.

    • A transflective display device has a viewing side (7) and a rear side (8) and comprises a plurality of electrowetting elements (2) having a first support plate (5) facing the viewing side and a second support plate (6) facing the rear side. Each electrowetting element comprises a space (10) between the first support plate and the second support plate and includes a first fluid (11) and a second fluid (12) immiscible with each other. The second fluid absorbs at least a part of the optical spectrum. The position of the second fluid is controllable to cover a predetermined area (30) of the cross-section (29) of the space in the plane of the second support plate. A structured reflector (18) is arranged on the second support plate, comprising within the cross-section an area (33, 34) transparent for light incident from the rear side and an area (35, 36) reflective for light incident from the viewing side. The transparent area and the reflective area are arranged such that the predetermined area (30) covered by the second fluid covers the same proportion of the transparent area and the reflective area.
