PURPOSE:To provide a polyamide compsn. which gives moldings having excellent resistance to surface staining with good workability, by incorporating a specified fluorine compd. having excellent thermal stability. CONSTITUTION:A metal salt of a sulfonic or carboxylic acid of a fluoroalkyl- contg. compd. contg. a perfluoroalkyl group of formula I or II [wherein Rf is a 4-18C perfluoroalkyl; X is S, O; Y is a benzene, naphthalene, diphenyl, or diphenyl ether nucleus, a group of formula III (wherein R' is H, a 1-3C alkyl); Z is -COO-, -SO3-; M is a mono-to tetravalent metal] such as sodium perfluorooctane sulfonate is used. 0.05-8wt% said fluorine compd. is melt-mixed with a polyamide such as nylon 6 or nylon 66. |
