Provided is a process for making a dispersion of composite particles comprising

Method for preparing polyolefin-acrylic particles

The present disclosure provides a process. The process includes (i) melt blending, in an extruder, (a) a polyolefin phase and (b) an aqueous phase in the presence of (c) at least one dispersant selected from an acrylic dispersant, a poloxamer dispersant, and combinations thereof; (ii) producing an interfacial tension from 0.1 dynes/cm to 25 dynes/cm; (iii) forming a polyolefin aqueous dispersion having from 25 wt % to 90 wt % solids content of dispersion; and (iv) removing the water from the polyolefin aqueous dispersion to form a powder. The powder has a mean volume average particle size from 10 &#x3bc;m to 300 &#x3bc;m, a sphericity from 0.92 to 1.0, a particle size distribution from 1 to less than 2, and a particle density from 98% to 100%.

Process for forming a powder

An improved polymer delivery system is described which provides polymeric microparticle compositions and porous microparticles formed therefrom. Pore size, pore architecture as well as particle size are also controllable. In some embodiments, both the polymeric microparticle compositions and porous microparticles formed therefrom encapsulate at least one substance, such as a biologic substance (one having biologic activity and/or compatible with a biologic system). The encapsulation occurs prior to polymerization. The amount of substance that is encapsulated may be controlled by the described methods. Said methods do not emply organic solvents. As such, the fabrication occurs in a solvent-free system.

Porous microparticles with high loading efficiencies

The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.

Recovery of additive manufacturing support materials

Materials and methods for preparing three dimensional scaffolds are described. The materials, as improved high internal phase emulsions (HIPES), and the polymerization thereof may be suitable for injection prior to curing and when in an injectable form may be for site-directed in vivo use, curing after injection. In addition, said materials before curing may be engineered as a tissue substitution or enhancement and/or to include cell encapsulation. Said materials described herein form a monolith after curing and are biodegradable and porous after curing. Said materials are made from starting molecules using a process that does not rely on toxic solvents or monomers. Making of said materials to form the emulsion take advantage of one or more surfactants for HIPE stability. In addition, said materials cure at temperatures appropriate for use in an in vivo or in situ environment.
