POLYESTER-BASED POLYMER POLYOL WITH AN EXCELLENT ANTI-FLAME PROPERTY AND A MANUFACTURING METHOD THEREOF

摘要

The present invention relates to the production of a superior polyester polymer polyol is excellent in dispersion stability, flame retardance. Was the polymer polyols were used to polyester polyol containing an aromatic compound instead of the polyester polyol using conventional adipic acid improved the flame retardancy by the addition of bromostyrene derivative flame retardancy is excellent, the dispersion stability by introducing a small amount of the dispersion stabilizer excellent mechanical strength and also to obtain a good polymer polyols. It is applicable to the field of floor waterproof materials requiring flame retardancy. ; Polymer polyols
