| 摘要 |
Weather resistant synthetic fibers of polyamide, polyester, polyethylene and polypropylene were manufd. by melt spinning process. Mixts. which were consisted of Mn compds. 0.005-0.07 and cyclic phophorous compds. 0.01-5% in wt. (I; R = C2-10 alkylene, C7-10 phenyl alkylene, phenylene, C7-10 cyclo alkylene, C3-5 alkylene; R' = hydrogen, alkyl, allyl, aralkyl; X,X' = oxygen or sulfur; n = 2-3) having 2-3 phosphorous chain were used as a weather resisting agent and showed good resistance character when added to the synthetic fiber polymer.
