Abstract: A modified phosphorus-containing unsaturated polyester being represented by Formula I is provided: wherein each A? is independently a residue of a diol or polyol, each B? is independently a residue of a saturated or unsaturated anhydride or acid, G1 and G2 are independently H or a residue of an isocyanate acrylate-based compound or isocyanate silicon-containing compound, with the proviso that G1 and G2 are not both H; and wherein a is an integer from 1 to 30, b is an integer from 1 to 30, and the modified phosphorus-containing unsaturated polyester has an OH value ranging from 50 to 200.

Abstract: The present invention is directed to a flame-retardant polyester having a structure of formula (I): where each A? is, independently, a residue of a diol, each B? and each B? may be identical or different and are, independently, a residue of a saturated or unsaturated anhydride or acid, and C? and C? may be identical or different and are independently selected from hydrogen, a residue of an epoxy acrylate compound or a residue of an epoxy silicon-containing compound, with the proviso that C? and C? are not both hydrogen, where a is an integer of from 1 to 30, b is an integer of from 1 to 30, and c is an integer of from 1 to 15, and where the flame-retardant polyester has an acid value of from 20 to 40. The present invention is also directed to a process for preparing the flame-retardant polyester and a composition including the same.
