| titleOfInvention | Method for producing polymer polyol |
| abstract | PROBLEM TO BE SOLVED: To find a method for producing a polymer polyol having a small particle diameter of polymer particles dispersed in a polyol and having excellent resin physical properties when used in a polyurethane resin. [Solution] A method for producing a polymer polyol (I) containing polymer particles, comprising the following steps (1), (2) and (n), wherein the sum of (B1) and (A2) in step (2) A method for producing a polymer polyol (I), wherein the concentration (% by weight) of (b) based on weight is 26 to 40. Step (1): polyol (a), ethylenically unsaturated monomer (b), radical polymerization opening Polymerization of monomer mixture (A1) consisting of initiator (c) and dispersant (d) Or polymerized product is diluted with (a), and the content of polymer particles Step (2) for obtaining a polymer polyol intermediate (B1) having a weight percentage of 7 to 15: In (B1), a monomer mixture (A2) comprising (b) and (c) is obtained. Step (n) for polymerizing to obtain a polymer polyol intermediate (B2): In the polymer polyol intermediate (B (n-1)), (b) and (c) A monomer polyol (An) is polymerized to form a polymer polyol intermediate ( Bn), or a step of obtaining the polymer polyol (I) (n is an integer of 3 to 7) Represents. ) [Selection figure] None |
