ABSTRACT:
The inclusion of a polymer containing rigid moieties in an active hydrogen-containing compound has surprisingly been found to yield significant and unexpected improvements in the physical properties of polyurethane and/or polyurea polymers prepared therefrom. In particular, cellular polyurethane and/or polyureas made from these solutions have excellent firmness and high moduli.
