NYLON 66 RESIN COMPOSITION CONTAINING TITANIUM OXIDE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a nylon 66 resin composition for fiber-making, which contains a large amount of titanium oxide uniformly dispersed in a fine particle. SOLUTION: The nylon 66 resin composition is obtained by adding 1 part. wt. to≤5 parts wt. of titanium oxide to 100 parts wt. of a nylon 66 resin in a temperature range of≥216°C and≤230°C in polymerization of a nylon 66 containing titanium oxide or in copolymerization of another polyamide consisting essentially of a nylon 66. The method for producing the nylon 66 resin composition is provided. COPYRIGHT: (C)2006,JPO&NCIPI
