US Patent:

41918126, Mar 4, 1980
Filed:

Sep 19, 1978
Appl. No.:

5/943891
Inventors:

Berni P. Chong - North Wales PA
Assignee:

Rohm and Haas Company - Philadelphia PA
International Classification:

C08J 300
B01D 1504
US Classification:

521 28

US Patent:

41513320, Apr 24, 1979
Filed:

Feb 2, 1978
Appl. No.:

5/874711
Inventors:

Berni P. Chong - Willow Grove PA
Robert R. Rowe - Warminster PA
Assignee:

Rohm and Haas Company - Philadelphia PA
International Classification:

B01J 109
US Classification:

521 28
Abstract:

Beads of an inert, crosslinked copolymer of methyl methacrylate and hydroxyalkyl methacrylate are used as an interface separator during the regeneration of mixed-bed ion exchange columns; the beads have a settling rate intermediate between that of the cation and anion exchange resins of the mixed-bed system.

US Patent:

43129560, Jan 26, 1982
Filed:

Jun 18, 1979
Appl. No.:

6/049538
Inventors:

Berni P. Chong - North Wales PA
Eric G. Isacoff - Richboro PA
James W. Neely - Horsham PA
Assignee:

Rohm and Haas Company - Philadelphia PA
International Classification:

B01J 4704
C02F 156
US Classification:

521 28
Abstract:

Flocs prepared by mixing cationic and anionic emulsion ion exchange resins are useful as a filtration and deionization medium. Flocs prepared from weakly acidic and weakly basic emulsion ion exchange resins may be regenerated thermally.

US Patent:

43595375, Nov 16, 1982
Filed:

Sep 19, 1978
Appl. No.:

5/944052
Inventors:

Berni P. Chong - North Wales PA
Assignee:

Rohm and Haas Company - Philadelphia PA
International Classification:

C08F 622
B01J 3920
B01J 4114
US Classification:

521 29
Abstract:

Emulsion copolymer particles with diameters less than 1. 5 micrometers are functionalized with anion exchange functional groups by a method involving coagulation of the emulsion. Both weakly basic and strongly basic anion exchange resins are prepared from aromatic or acrylic copolymers, and the emulsion coagula may be resuspended to form anion exchange emulsions.

US Patent:

42657687, May 5, 1981
Filed:

Dec 26, 1979
Appl. No.:

6/107114
Inventors:

Glenn H. Beasley - Newtown PA
Berni P. Chong - Dresher PA
Warren T. Ford - Stillwater OK
James W. Neely - Dresher PA
Assignee:

Rohm and Haas Company - Philadelphia PA
International Classification:

B01J 3924

US Classification:

210682
Abstract:

Macroporous styrene polymer particles which have been partially pyrolyzed at temperatures between 300. degree. and 800. degree. C. to form non-functionalized, carbonaceous adsorbents, are functionalized according to this invention to produce weak base, strong base, weak acid or strong acid, dense ion exchange particles, or precursors thereof, using such reactions as halogenation, sulfonation, chloromethylation, chlorosulfonation and oxidation, alone or followed by aminolysis or other conventional functionalization reactions.
