Description	High solids polymer polyols are widely used in the polyurethane industry for the purpose of enhancing the load bearing capacity. The most widely used polymer polyols consist of stable dispersions of styrene and acrylonitrile copolymer particles. The technology for producing these polymer polyols continues to advance to meet the needs of new polyurethane foam applications. Recent polyurethane foam industry requires high solids polymer polyol to enhance the load bearing capacity of a wide variety of foam types (slabstock, HR, RIM, semi-flexible, etc.). High polymer content (over 45wt%), good filterability and low viscosity are the key requirements. When polymer content is high, polymer polyol's viscosity is high too. When polymer content is 50 weight %, polymer polyol's viscosity is over 10,000mPav s. But polyurethane foam industry requires high solids polymer polyol with low viscosity. We found the process that can reduce the viscosity of high solids polymer polyol. In this paper we present Sanyo's new polymer polyol that has high polymer content such as 50 weight % and low viscosity such as 4,800mPa · s at 25°C. Book Name: Polyurethanes Expo 2001
