Title:
METHOD FOR PRODUCING FLAME-RETARDANT POLYESTER POLYMER, POLYMER PRODUCED THEREBY AND FIBER PRODUCED THEREFROM
Document Type and Number:
Japanese Patent JP2008127570
Kind Code:
A
Abstract:
To provide a method for producing a polyester polymer that has permanent flame retardancy, particularly excellent stability against UV (ultraviolet rays), a polymer produced therefrom and fiber produced by using the same.
In the method for producing a flame-retardant polyester polymer, a phosphorus flame-retardant, namely a propionic acid substituted with phosphorus-including group on the -position is cast in so that the amount may become 500 to 50,000 ppm to the polyester polymer calculated as phosphorus atom at the secondary esterification reaction step, and a manganese salt and a phosphorus compound as UV stabilizers are cast individually in an amount of 0.1 to 500 ppm in terms of manganese atom and phosphorus atom.
