Abstract
A composition for increasing flame resistance of a step-reaction polymer comprising a metal salt of certain organic acids in combination with certain organic acids or their ammonium salts, the method of treating the step-reaction polymer with the composition and the resulting treated polymer.
Claims9
A polymer selected from the group consisting of nylon, polyester and polyurethane, said polymer having from about 1 to 15 weight percent of a composition added thereto, said composition comprising:
- a. from about 20 to 80 weight percent of a metal salt of a hydrocarbyl hydroxycarboxylic acid;
- and
- b. from about 20 to 80 weight percent of a metal free organic compound selected from the group consisting of hydrocarbyl hydroxycarboxylic acids and their ammonium salts.
