Patent ID: 8415415

Claim:
A flame retardant composition comprising: A. at least one copolyester thermoplastic elastomer; B. from at or about 1 to at or about 30 weight percent, based on the total weight of the flame retardant composition, of at least one flame retardant selected from the group consisting of phosphinates of formula I, diphosphinates of formula II, polymers thereof and combinations of two or more thereof wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, linear or branched C 1 -C 6 alkyl groups, and aryl groups; R 3 is a linear or branched C 1 -C 10 -alkylene group, a C 6 -C 10 -arylene group, a C 6 -C 10 -alkylarylene, or a C 6 -C 10 -arylalkylene group; M is a metal ion selected from the group consisting of calcium ions, magnesium ions, aluminum ions, zinc ions, and mixtures thereof, m is 2 to 3; n is 1 or 3; and x is 1 or 2 with the proviso that when m is 2 in formula II, then x and n are each 1, and when m is 3, x is 2 and n is 3; and C. from at or about 0.25 to at or about 15 weight percent, based on the total weight of the flame retardant composition, of one or more polyhydroxy polymers having a number average molecular weight of at least 2000, selected from the group consisting of ethylene vinyl alcohol copolymers and poly(vinyl alcohol)s.
