Abstract: The invention is directed to fluorinated particles having adsorbent properties for superior performance as the stationary phase for use in chromatographic separations. In particular, the fluorinated surface of such particles of the invention presents unusual and unexpected polarity that is beneficial in performing chromatographic separations such as that used for DNA.

Abstract: A process to make particles by anaerobic reaction of a water-insoluble solution of organic compounds comprising (a) a monomer selected from C2-4 alkylene glycol esters of a C3-6 acrylic acid and a divinyl benzene; (b) a polyfluorinated vinyl monomer; (c) a monomer selected from acrylic acid, methacrylic acid and esters thereof; (d) a free radical initiator; and (e) a water-insoluble, organic solvent-soluble porogenic material, the weight ratio of comonomers (a) plus (b) plus (c) to the porogenic material being from 0.5:1 to 2:1. The adsorbent particles produced by the process are useful in carrying out chromatographic separations, or in the production of medical devices.

Abstract: Disclosed herein is a process for preparing highly filled acrylic articles comprising:(a) providing a solution of an acid-functional acrylic polymer-in-monomer solution;(b) mixing into said solution a catalytic amount of polymerization promoter system;(c) blending into said mixture 40 percent to 80 percent inert particulate filler to form a casting mixture;(d) introducing said casting mixture to a mold; and(e) curing said molded casting mixture;whereby the viscosity of said casting mixture is controlled and the settling of said filler is minimized by the presence of units from said carboxylic acid in said polymer.

Abstract: Compositions which cure at room temperature comprising an acrylic polymer dissolved in an acrylic monomer, a cross-linking monomer, hydrated alumina, fibrous reinforcement, a free radical catalyst and a catalyst promoter for use in rigidizing acrylic sheet and gel coats.

Abstract: A foamed cementitious material comprising portland cement and a film-forming, water-resistant, alkali-stable emulsion polymer and process of preparing said foamed material is described. Also described are laminated cementitious composites of an unfoamed veneer of a mixture of portland cement and a film-forming, water-resistant, alkali-stable emulsion polymer applied at the surface of a layer of the above-described foamed cementitious material, and, optionally, a layer of plywood or metal further applied at the exposed foamed material surface are described. These materials are useful as exterior building covering articles.

Abstract: Foamed thermoset articles are produced by introducing a thermosettable organic resin, a specific class of blowing agents, inorganic particulate filler, and glass fiber in a mold at a given temperature and pressure, and then lowering the mold pressure to a predetermined reduced pressure to cause foaming, and completing the foaming before gelation. The foamed thermoset articles are also disclosed.
