Abstract

The present invention relates to low triphenyl phosphate, high phosphorous content aryl phosphates with high ortho alkylation that are suitable for use as flame retardant compositions, processes for their preparation, and their use as flame retardants.

Claims (10)

1. An alkylated triaryl phosphate ester comprising:

a) in the range of from about 90 to about 92 wt. % isopropylphenyl diphenyl phosphate, in the range of from about 0.5 to about 0.75 wt. % triphenyl phosphate, in the range of from about 1 to about 3 wt. % diisopropylated triphenyl phosphate, in the range of from about 0.05 to about 0.15 wt. % triisopropylated triphenyl phosphate, and in the range of from about 0.5 to about 0.75 wt. % 2,4-diisopropylphenyl diphenyl phosphate;

or

b) in the range of from about 94 to about 96 wt. % isopropylphenyl diphenyl phosphate, in the range of from about 3.5 to about 5.5 wt. % diisopropylated triphenyl phosphate, and in the range of from about 0.1 to about 0.3 wt. % triisopropylated triphenyl phosphate;

or

c) in the range of from about 71 to about 73 wt. % isopropylphenyl diphenyl phosphate, in the range of from about 0.05 to about 0.15 wt. % triphenyl phosphate, in the range of from about 26 to about 28 wt. % diisopropylated triphenyl phosphate, and in the range of from about 0.5 to about 0.7 wt. % triisopropylated triphenyl phosphate.

2. A composition comprising (i) the alkylated triaryl phosphate ester of claim 1 , and (ii) a polymer resin, an isocyanate or a polyol.

3. The composition of claim 2 , wherein said polymer resin is (i) one or more vinylaromatic homopolymers or copolymers, (ii) one or more acyclic olefinic hydrocarbon homopolymers or copolymers; and (iii) one or more copolymers of at least one vinylaromatic monomer and at least one non-vinylaromatic monomer containing a functional group, wherein said non-vinylaromatic monomer is selected from a group consisting of acrylonitrile, an acrylate monomer and a methacrylate monomer.

4. The composition of claim 2 , wherein (ii) is polyvinylchloride.

5. The composition of claim 2 , wherein (ii) is an isocyanate or a polyol.
