Abstract
The flame resistance of synthetic fibers and solid polymers are improved by treatment with a halogen containing amide having the formula ##STR1## wherein R is lower alkoxy; lower alkoxy carbonyl; ##STR2## X is chlorine or bromine; m is 0 or 1; n is 1-6; and y is 1-13.
Claims7
A halogen containing amide of the formula ##STR14## wherein R is lower alkoxy,
- lower alkoxy carbonyl,
- +N(C.sub.n H.sub.2n+1-y X.sub.y).sub.2, ##STR15## X is chlorine or bromine;
- m is 0 or 1;
- n is 1-6;
- y is 1-13;
- and
- when R is lower alkoxy and n is 1 and m is 0, y is 2-3.
