Stable aqueous dispersions or emulsions can be prepared by merging into a mechanical disperser a stream of a molten or liquid disperse phase with a stream of a molten or liquid continuous phase to form a dispersion or emulsion. The molten or liquid disperse phase stream contains a polymer that is preferably a solid at room temperature, but molten at some advanced temperature. The polymer is formed in a molten state or formed and melted by a continuous reaction process such as an extrusion process, including melt extrusion or compound extrusion. It has been discovered that low polydisperse submicron sized dispersion can be prepared by the method of the present invention.

Continuous process of extruding and mechanically dispersing a polymeric resin in an aqueous or non-aqueous medium

Process for preparing polybenzazole filaments and fiber

A RIM apparatus has a separate hydraulically actuated monomer dispensing system associated with one of at least two different fluid chemical monomers to be mixed and molded. Each system is connected with a separate hydraulic fluid delivery cylinder (one for each monomer) for receiving hydraulic fluid therefrom and is operable for dispensing the associated monomer to a RIM mixing head and mold at a rate proportional to the rate that said hydraulic fluid is delivered thereto from the connected delivery cylinder. Each delivery cylinder is supported at a preselected position with its axis spaced radially from a reference axis and at least one thereof is bodily adjustable radially with respect to said reference axis and to the axis of another delivery cylinder. Each delivery cylinder discharges hydraulic fluid at a rate proportional to the rate of movement of an associated piston therein. A power driven operator is engaged with each said associated piston for effecting said movement at a rate proportional to the distance between the axis of the associated delivery cxylinder and said reference axis. Valve means enables selective interconnection between the delivery cylinders and dispensing systems in various combinations.
