Process For Making Fluorinated Polymer Adsorbent Particles
View pageUS Patent:
6573307, Jun 3, 2003
Filed:
Apr 15, 2002
Appl. No.:
09/980901
Inventors:
Leonard H. Smiley - Philadelphia PA
Christopher Lowe - Cambs, GB
Julie Tucker - Kent, GB
Christopher Lowe - Cambs, GB
Julie Tucker - Kent, GB
Assignee:
Prometic Biosciences, Inc. - Montreal
International Classification:
C08J 926
US Classification:
521 64, 264 41, 264 42, 521150
Abstract:
A process to make particles by anaerobic reaction of a water-insoluble solution of organic compounds comprising (a) a monomer selected from C alkylene glycol esters of a C 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.
Use Of Adsorbent Polymer Particles In Dna Separation
View pageUS Patent:
6746608, Jun 8, 2004
Filed:
Dec 12, 2002
Appl. No.:
10/317980
Inventors:
Leonard H. Smiley - Philadelphia PA
Assignee:
Prometic Biosciences, Inc.
International Classification:
B01D 1500
US Classification:
210656, 210661, 210679, 536127, 521145
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.

Foamed Thermoset Articles And Processes
View pageUS Patent:
40268284, May 31, 1977
Filed:
Jun 13, 1975
Appl. No.:
5/587196
Inventors:
Leonard H. Smiley - Jenkintown PA
Assignee:
Rohm and Haas Company - Philadelphia PA
International Classification:
B29D 2700
US Classification:
260 25N
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.

Foamed Cementitious Material And Composite
View pageUS Patent:
41139135, Sep 12, 1978
Filed:
May 13, 1976
Appl. No.:
5/686193
Inventors:
Leonard H. Smiley - Jenkintown PA
Assignee:
Rohm and Haas Company - Philadelphia PA
International Classification:
C04B 1502
US Classification:
428310
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.
Process For Preparing Highly Filled Acrylic Articles
View pageUS Patent:
41839919, Jan 15, 1980
Filed:
May 2, 1977
Appl. No.:
5/793229
Inventors:
Leonard H. Smiley - Jenkintown PA

Howard L. Tigelaar - Levittown PA
Assignee:
Rohm and Haas Company - Philadelphia PA
International Classification:
B29D 700
US Classification:
428220
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.
