A flame retardant composition is provided which contains at least one phosphate ester containing at least one acidic substance resulting from the process of its manufacture, at least one acidity-reducing hydrotalcite and, optionally, at least one acidity-reducing oxetane. The flame retardant composition is especially useful for addition to resins that are susceptible to hydrolytic degradation such as polyesters and polycarbonates, and to resin blends (alloys) containing one or more of such resins, e.g., a blend of polycarbonate and acrylonitrile butadiene-styrene terpolymer.

Flame retardant composition and hydrolysis-susceptible resin containing same

An oligomeric phosphate or mixture of oligomeric phosphates having the general formula (I) wherein R, R, Rand Reach independently is aryl or alkaryl and n has an average value of from about 1.0 to about 2.0 and resin compositions containing the same. 

Oligomeric bisphosphate flame retardants and compositions containing the same

A vinyl chloride resin composition contains, as the major plasticizer, a neopentyl glycol bis(diphenyl phosphate) composition in an amount that is no less than about 25% by weight, based upon the vinyl chloride resin being present at 100%, by weight.

Vinyl chloride polymer/neopentyl glycol bis(diphenyl phosphate) compositions

A vinyl chloride polymer composition that contains a mixture of an alkylene-bridged bisphosphate composition, as a fire retardant, and a polyester plasticizer, which is the reaction product of an aliphatic diol and a dicarboxylic acid.

Alkyl-aryl oligomeric phosphate ester and polymeric plasticizer blends for vinyl resins

The present invention is a flame retardant polyketone polymer composition which comprises: (a) a bicyclic phosphorus flame retardant compound, such as one containing one or more pentaerythritol phosphate alcohol moieties, as exemplified by bis(pentaerythritol phosphate alcohol) carbonate; (b) an intumescent flame retardant compound containing nitrogen and phosphorus, such as melamine phosphate; and (c), optionally, a monophosphate ester compound to enhance the compatibility of the composition in the polymer substrate, such as a liquid aryl-group containing phosphate ester compound or melamine phosphate, and the monophosphate ester compound is triphenyl phosphate.

Flame retardant polyketone composition

The present application relates to a flame retarded polycarbonate resin composition containing for flame retardancy a hydroxy-terminated aromatic oligomeric phosphate composition of the formula: ##STR1## where R is a hydrocarbyl group derived from an aliphatic or aromatic diol, Ar is an alkyl-substituted or unsubstituted phenyl group, n is from about 0 to about 10, and the phosphate composition contains a predominant amount of phosphate where n ranges from 0 to 1.

Hydroxy-terminated aromatic oligomeric phosphate as additive flame

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:
