Filed:
Jan 19, 1977
Appl. No.:
5/761141
Inventors:
Henry Gisser - Philadelphia PA
Helen Mertwoy - Dresher PA
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
C08F 446
C08F22068
C08F22010
C08F22014
US Classification:
526328
Abstract:
Copolymers are formed by reacting methyl methacrylate and methyl. alpha. -lkylacrylate between 20. degree. -30. degree. C in presence of catalytic amounts of sodium, the alkyl group in the methyl. alpha. -n-alkylacrylate having from 10 to 22 carbon atoms.

US Patent:
39728641, Aug 3, 1976
Filed:
Feb 19, 1975
Appl. No.:
5/551185
Inventors:
Henry Gisser - Philadelphia PA
Helen E. Mertwoy - Dresher PA
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
C08F22010
C08F22014
US Classification:
526328
Abstract:
Methyl methacrylate and methyl. alpha. -n-alkylacrylate wherein the alkyl up may vary from 10 to 22 carbon atoms copolymerize at about 50. degree. C in the presence of azobisisobutyronitrile to form polymers having low coefficients of friction and good wear properties.

Copolymers Of Alpha-N-Alkylstyrenes And Styrene

US Patent:
41951441, Mar 25, 1980
Filed:
Oct 19, 1978
Appl. No.:
5/952873
Inventors:
Helen E. Mertwoy - Dresher PA
Henry Gisser - Philadelphia PA
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
C08F21208
US Classification:
526173
Abstract:
There is described novel copolymers of styrene and alpha-n-alkylstyrenes taining at least eleven carbon atoms in the alkyl group. The copolymers, which contain at least 20 mole percent of the alpha-n-alkylstyrenes, are solids and have greater durability with lower coefficients of friction than comparable styrene homopolymers. The copolymers are produced by anionic initiated copolymerization using metallic sodium as the catalyst or by radical initiated copolymerization using benzoyl peroxide or azobisisobutyronitrile as the catalyst.
