Abstract
Polymer polyols ('PMPOs'), processes for their production, and the use of such PMPOs, particularly in the production of flexible polyurethane foams. The PMPOs are produced using an ethylenically unsaturated composition that includes a crosslinker that results in crosslinks in the PMPO polymer particles that may decompose when exposed to flame temperatures. The PMPOs is capable of providing a flexible polyurethane foam that may exhibit combustibility resistance properties.
