Abstract:

The present disclosure provides for a metal chelated polyol liquid and/or a metal chelated polyether polyol liquid that can be used in an isocyanate-reactive composition and a reaction mixture for forming a polyurethane polymer. The metal chelated polyester polyol liquid is a reaction product of a chelating polyester polyol having a chelating moiety and a metal compound having a metal ion. The metal chelated polyether polyol liquid is a reaction product of a chelating polyether polyol having a chelating moiety and a metal compound having a metal ion. The chelating moiety of the chelating polyester polyol or the chelating polyether polyol chelates the metal ion to form the metal chelated polyester polyol liquid or the metal chelated polyether polyol liquid, respectively, having a mole ratio of the metal ion to the chelating moiety of 0.05:1 to 2:1.
