US Patent:

48551279, Aug 8, 1989
Filed:

May 20, 1987
Appl. No.:

7/053609
Inventors:

Eric S. Abrutyn - Middletown NY
Louis Scarfo - New Britain CT
Richard Chromecek - Litchfield CT
Assignee:

Dow Corning Corporation - Midland MI
International Classification:

A61K 7035
A61K 740
A61K 742
A61K 970
US Classification:

424411
Abstract:

This invention relates to solid compositions wherein a non-cosmetic functional material is entrapped in the lattice of the cross-linked polymer during in situ polymerization of the monomers forming the polymer lattice. The invention provides for conversion of solid and/or liquid products into solid, free-flowing forms by entrapment of the functional materials in a hydrophobic polymer lattice.

US Patent:

51263092, Jun 30, 1992
Filed:

Jul 5, 1990
Appl. No.:

7/548526
Inventors:

Richard C. Chromecek - Litchfield CT
John C. McMahon - New Windsor NY
Milan F. Sojka - Walden NY
Assignee:

Dow Corning Corporation - Midland MI
International Classification:

B01J 2026
US Classification:

502402
Abstract:

A process of decontaminating a surface contaminated with a toxic chemical agent in which there is applied to the contaminated surface, a macroporous cross-linked hydrophobic copolymer containing an agent which is a decontaminant for the toxic chemical agent present on the surface. The decontaminant can be a chemical neutralizer such as sodium hydroxide; lithium hydroxide; concentrated bleach; and mixtures of diethylene triamine, 2-methoxy ethanol, and sodium hydroxide, for example.
