摘要：This invention relates to the process for the preparation of polyurethane withcontrolled particle size and shape. More, particularly it relates to the production ofpolyurethane microspheres from a diol and diisocyanate by dispersion polymerization inpresence of a steric stabilizer and a catalyst in an organic solvent at a controlledtemperature, and finally separating the spherical polyurethane particles from thereaction mixture by conventional means.
