FLAME RETARDED, STABILIZED POLYESTER COMPOSITION

摘要

Flame retarded and stabilized polyester composition contain: (a) a polyester resin derived from a cyclohexanemethanol and a carbocyclic acid; (b) a polyphosphate containing a bridging unit between the phosphate moieties therein which is derived from an arylene-containing diol; and (c) a stabilizer which is either: (i) a combination of a hindered phenol-substituted isocyanurate and an epichlorohydrin-bisphenol A reaction product; or (ii) a combination of an ester of a hindered phenol and oxidized polyethylene; when the arylene-containing diol is a monoarylene-containing diol, such as resorcinol or hydroquinone; or (iii) a hindered phenol-substituted isocyanurate; or (iv) a phenolic oxamide antioxidant; or (v) combination of a hindered phenol-substituted isocyanurate and an epichlorohydrin-bisphenol A reaction product; or (vi) combination of an ester of a hindered phenol and oxidized polyethylene; when the arylene-containing diol is a biarylene-containing diol with an alkylene bridging group between the two arylene groups, such as bisphenol A.
