A process involving, for example, the admixing of an emulsion latex, a colorant, and a tetra-alkylated quaternary ammonium halide salt complexing agent; and thereafter, heating in sequence about below the Tg of a resin contained in the latex and then heating about above the Tg glass transition temperature of a resin contained in the latex.

The invention provides for a process to produce polymers utilizing a hydrofluorocarbon diluent.

The invention provides for polymerization processes to produce polymers utilizing boiling pool reactor systems and diluents including hydrofluorocarbons.

A toner process comprising aggregating or coagulating a latex emulsion comprising a resin, a colorant and wax particles using an amount of polymetal ion coagulant to provide core particles; heating the core particles to provide micron size aggregates; optionally adding a second resin emulsion; adding a sequestering or complexing component and a base to remove the polymetal ion in a controlled manner; further heating the mixture to provide toner particles; and optionally, isolating the toner part...

Processes for continuously forming latex emulsions and preparing toners with said emulsions are provided.

A process for separating a gas component from a gas mixture is disclosed. A gas mixture is passed through an adsorption zone which contains an adsorbent which will selectively adsorb a gaseous component from the gas mixture. The adsorption zone contains a layer of monolithic adsorbent and a layer of adsorption beads. Optionally, a third monolithic layer may be employed. The adsorption zone is typically contained in an adsorption vessel.

A process for the preparation of a latex polymer consistent with E/A (emulsion/aggregation/coalescence) toner manufacture. The process utilizes a standard (universal) latex composition and involves chain-transfer agent partitioning, emulsion polymerization that provides a latex polymer with a wide range of molecular properties. In particular, the process customizes a wide range M.sub.w (weight average molecular weight) latex, without substantially varying the M.sub.n (number average molecular we...

The gas originating from the expansion during the stage (T.sub.6) is directed into a buffer tank and each adsorber has an operating cycle delayed by 1/nth of the cycle period (T) with respect to a preceding one, and each production stage has a duration of (x/n)T, "n" being greater than or equal to 6, and "x" greater than or equal to 2, and each expansion stage at an intermediate pressure has a shorter duration than each elution stage.

The invention relates to various energy saving measures for use in the smelting, refining and melting of metals, and in particular in the manufacture of steels, alloy steels and ferrous alloys. In such processes fuel consumption is reduced and efficiency improved by using in the oxy-fuel or air-fuel burner a fuel (referred to as an "X-type" fuel) which has an exothermic heat of decomposition or which has only a zero or a very small endothermic heat of decomposition. The invention also relates to...

A toner process comprising mixing an acidified dispersion of an acicular magnetite with an anionic latex, an anionic carbon black dispersion, and an anionic wax dispersion.
