Semi‐suspension polymerization process

Macromolecular Symposia, 1996
AbstractA novel heterogeneous polymerization process for synthesizing particulate with a wide range of properties has been developed. This process, which is called semi ‐ suspension polymerization (SSP), consists of two steps. In the first step a mixture of monomer, polymer, initiator, and other required ingredients is prepared by means of a non ...

Electroactivity of polymeric suspensions

SPIE Proceedings, 2007
Two types of the electroactive response in polymeric suspensions can be considered - dielectrostriction and piezoresistance. Dielectrostriction is a variation of dielectric properties of a material with deformation while piezoresistance involves a change in conductivity with deformation.

Suspension polymerization of caprolactam

Journal of Applied Polymer Science, 1965
AbstractThe anionic polymerization of caprolactam (with sodium hydride and acetyl caprolactam as catalysts) carried out in glass ampules is reported. The effect of the catalyst concentration, polymerization temperature, and other variables was studied. Polymerization of caprolactam at temperatures around 120°C.

Micron‐sized polymeric microsphere by suspension polymerization

Journal of Applied Polymer Science, 1993
AbstractA new suspension polymerization process that generates narrow‐size distribution and spherical particles in the range of 3–10 microns is described. In the new process, the monomer and water phases are held in separate vessels and fed at an accurate rate to a mechanical disperser, where small, uniform droplets of monomer are formed.

DROP DISPERSION IN SUSPENSION POLYMERIZATION

Chemical Engineering Communications, 1982
Four models, two based on laminar shear and two based on turbulent flow, are proposed to describe drop dispersion in non-coalescing systems. The models predict the largest surviving drop size dmax as a function of geometry, speed and physical property variables. Laboratory data including suspension polymerization runs support the boundary layer laminar

Chlorotrifluoroethylene Suspension Polymerization

2002
Polychlorotrifluoroethylene (PCTFE) is ordinarily prepared by emulsion polymerization. A polymer suitable for thermal processing requires coagulation, extensive washing, and postpolymerization workup. Coagulation to provide a filterable and washable solid is a slow, difficult process and removal of surfactant is an important part of it.

Acrylonitrile polymerization in aqueous suspension

Journal of Polymer Science, 1957
AbstractPolymerization of acrylonitrile in dilute aqueous solution initiated by the chloratesulfite redox was studied kinetically and with the aid of the electron microscope. Polymerization rate depended on the [ClO] [H2SO3] product, the monomer content and the sodium lauryl sulfate concentration.
