US Patent:

39364925, Feb 3, 1976

Filed:

Aug 9, 1974

Appl. No.:

5/496320

Inventors:

Carlos M. Samour - Wellesley Hills MA
Mildred C. Richards - Wakefield MA

Assignee:

The Kendall Company - Walpole MA

International Classification:

C07C 8730

US Classification:

260482R

Abstract:

A novel class of monomeric emulsion stabilizers consists of certain types of ethylenically-unsaturated radicals covalently linked to a quaternary nitrogen atom which in turn is covalently linked to a lipophilic radical. Such monomers will polymerize with other ethylenically-unsaturated radicals forming self-stabilized, surfactant-free polymeric dispersions.

US Patent:

40511588, Sep 27, 1977

Filed:

Dec 11, 1975

Appl. No.:

5/640110

Inventors:

Carlos M. Samour - Wellesley MA
Mildred C. Richards - Wakefield MA

Assignee:

The Kendall Company - Boston MA

International Classification:

C07C10124

US Classification:

2604045

Abstract:

Quaternary ammonium salts having a lipophilic group covalently linked to the quaternary nitrogen through hydroxysuccinyloxy or hydroxysuccinylamino radicals are disclosed. These quaternary ammonium salts are useful as monomeric emulsion stabilizers.

US Patent:

39910083, Nov 9, 1976

Filed:

Aug 12, 1974

Appl. No.:

5/496769

Inventors:

Samuel C. Temin - Needham MA
Mildred C. Richards - Wakefield MA

Assignee:

The Kendall Company - Boston MA

International Classification:

C08K 554
C08K 536

US Classification:

260 4215

Abstract:

Dental compositions having improved color stability are prepared by employing a redox catalyst system consisting of a hydroperoxide oxidizing agent and a substituted thiourea reducing agent. The composition also comprises a methacrylate monomer, and optionally, a filler and a coupling agent.
