POLYMER POLYOL FOR MEMBRANE MODULE URETHANE RESIN SEALING MATERIAL

摘要

Provided is a polymer polyol for a    membrane module urethane resin sealing material which makes it possible to offer excellent heat resistance and oxidation stability while generating little heat.  The polymer polyol is obtained by dispersing polymer microparticles (p) in a polyol dispersion medium (b), which comprises castor oil and/or a castor oil derivative (a).  Further provided is a urethane resin moldable composition obtained using the polymer polyol, and a membrane module sealing material obtained by curing the composition.
