Polymer/polyols and process for production thereof

摘要

This invention relates to a novel process for producing polymer/polyols characterized by the use of specific combinations of acrylonitrile and styrene and by utilizing certain peroxyester catalysts. Methacrylonitrile and/or alpha-methyl styrene may optionally be used as substitutes for the acrylonitrile and styrene, respectively. The process produces novel polymer/polyols characterized by relatively high polymer contents and increased stability. These polymer/polyols are stable, fluid, essentially free from scrap and seeds as produced and contain relatively small polymer particles such that, in the preferred embodiment, essentially all are less than about 30 microns in diameter.
