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.

摘要： This invention relates to novel liquid polymer/polyol compositions consisting essentially of (1) a major amount of a polyol and (2) a minor amount of an acrylonitrile-vinylidene chloride polymer consisting essentially of (a) from 45 to 5 weight percent of polymerized vinylidene chloride and (b) from 55 to 95 weight percent of another polymerized monomer of monomers of which at least 20 weight percent is polymerized acrylonitrile, said weight percents being based on the weight of the polymer, and said polymer being in the form of particles that are stably dispersed in the polyol. The polymer/polyol compositions are prepared by a free radical catalyst initiated continuous process carried out at a temperature of 100.degree. C. or higher. The novel polymer/polyols are convertible to novel polyurethane products such as high resilience polyurethane foams having improved flammability characteristics.
