摘要： DISCLOSED ARE FLAME RETARDANT TEXTILE FIBERS COMPRISING AD ADMIXTURE OF A POLYESTER AND AN ADDITION POLYMER HAVING THE

-COO-CH2-C(-CH2-BR)3

GROUPS AS A PORTION OF THE POLYMER UNIT. THE POLYESTER IS DERIVED FROM AT LEAST 90 MOLE PERCENT TEREPHTHALIC ACID AND AT LEAST 90 MOLE PERCENT ETHYLENE GLYCOL, TETRAMETHYL ENE GLYCOL, OR 1,4-CYCLOHEXANEDIMETHANOL. THE ADDITION POLYMERS PREFERABLY COMPRISES AT LEAST 95 MOLE PERCENT UNITS OF THE STRUCTURE

-(CH2-CH(-COO-CH2-C(-CH2-BR)3))N-

THE TEXTILE FIBERS OF THIS INVENTION ARE FLAME RETARDANT AND EXHIBIT A DESIRABLE AND UNOBVIOUS COMBINATION OF OTHER PROPERTIES NECESSARY IN A COMMERICALLY ACCEPTABLE TEXTILE FIBER.
