## Abstract

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.

## Claims

### Claim 1

A vinyl chloride polymer composition that comprises 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.

### Claim 2 (depends on 1)

A composition as claimed in claim 1 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate).

### Claim 3 (depends on 1)

A composition as claimed in claim 1 wherein the polyester plasticizer is the reaction product of 1,4-butanediol and a mixture of glutaric and azelaic acid.

### Claim 4 (depends on 1)

A composition as claimed in claim 1 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate) and the polyester plasticizer is the reaction product of 1,4-butanediol and a mixture of glutaric and azelaic acids.

### Claim 5 (depends on 1)

A composition as claimed in claim 1 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate) and the polyester plasticizer is the reaction product of 1,4-butanediol and an equimolar mixture of glutaric and azelaic acids.

### Claim 6

A vinyl chloride polymer composition that comprises a mixture of from about 5 to about 70 parts by weigh weight of an alkylene-bridged bisphosphate composition, as a fire retardant, and from about 5 to about 120 of a polyester plasticizer, which is the reaction product of an aliphatic diol and a dicarboxylic acid, all weight amounts being based on 100 parts by weight or vinyl chloride polymer.

### Claim 7 (depends on 6)

A composition as claimed in claim 6 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate).

### Claim 8 (depends on 6)

A composition as claimed in claim 6 wherein the polyester plasticizer is the reaction product of 1,4-butanediol and a mixture of glutaric and azelaic acid.

### Claim 9 (depends on 6)

A composition as claimed in claim 6 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate) and the polyester plasticizer is the reaction product of 1,4-butanediol and a mixture of glutaric and azelaic acids.

### Claim 10 (depends on 6)

A composition as claimed in claim 6 wherein the alkylene-bridged bisphosphate composition comprises neopentylene bis(diphenyl phosphate)and the polyester plasticizer is the reaction product of 1,4-butanediol and an equimolar mixture of glutaric and azelaic acids.
