US Patent:

40596532, Nov 22, 1977

Filed:

May 27, 1976

Appl. No.:

5/690806

Inventors:

Ronald D. Mathis - Taylors SC
James S. Dix - Greenville SC

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C08L 7700

US Classification:

260857PG

Abstract:

In polyamide compositions containing the reaction product of (1) a block copolymer of propylene oxide, ethylene oxide, and an alkylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the apparent dyeability can be increased by including in said polyamide composition a sufficient amount of at least one zinc sulfinate of the formula: Zn(R"SO. sub. 2). sub. 2 wherein R" is an alkyl group containing from 4 to 20 carbon atoms.

40439720, Aug 23, 1977

Filed:

Oct 6, 1975

Appl. No.:

5/620085

Inventors:

Ronald D. Mathis - Taylors SC

Assignee:

Phillips Fibers Corporation - Greenville SC

International Classification:

C08J 320
C08L 300
C08K 550

US Classification:

260 459NC

Abstract:

In polyamides containing the reaction product of (1) a propylene oxide-ethylene oxide block copolymer based on ethylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the tensile strength loss on exposure to heat is reduced by adding a thermal stabilizing amount of a phosphine oxide.
