Abstract:
Provided is a method of preparing a polymer polyol including steps of (a) respectively batchwise feeding a polyol and a monomer in a weight ratio of 40 to 60:40 to 60 into a reactor to prepare a mixture; and (b) polymerizing the mixture for 1 to 5 hours to prepare monodispersed particles.
