Claims
- 1. A method for increasing the flame resistance of a member selected from the group consisting of fabrics, paper and adhesives comprising applying thereto a liquid poly(chloroethylethyleneoxy) phosphoric acid ester prepared by reacting tris(2-chloroethyl) phosphate by heating said phosphate to a temperature within the range of from about 140.degree. to about 220.degree. C. in the presence of a basic catalyst with ethylene dichloride as reaction by-product; and terminating said reaction by-product level with ethylene dichloride in an amount of from about 0.5 mole to about 0.9 mole ethylene dichloride per mole of tris(2-chloroethyl) phosphate in said reaction in an effective amount sufficient to increase the flame resistance of said member.
- 2. The method as recited in claim 1 wherein said liquid poly(chloroethylethyleneoxy) phosphoric acid ester is post treated with an alkylene oxide to neutralize the acidity in said product.
- 3. The method as recited in claim 1 wherein said member is fabric.
- 4. The method as recited in claim 1 wherein said member is paper.
- 5. The method as recited in claim 1 wherein said member is adhesives.
