Process for reducing residual monomers in low viscosity polymer-polyols. |
摘要 |
<p>An improved process is provided for preparing stable low viscosity polymer-polyols containing less than about 100 ppm residual monomers by using a monoperoxycarbonate initiator in combination with at least one initiator selected from diperoxyketals and peroxyesters, as chaser catalysts, at or near the end of the polymerization. The polymer-polyols prepared by the instant invention can be used to prepare high resiliency (load bearing) polyurethane foams.</p> |
