ABSTRACT:
A polyurethane containing an oligomer of a molecular weight of at most 5,000, which has at least either urethane or urea bonds, is terminated with inactive groups and does not have any group reactive with alcoholic hydroxyl and isocyanate groups of raw materials for urethane preparation in its molecule, at most in an amount not to cause deterioration of the desired characteristics of the polyurethane. The polyurethane of the present invention generates less static electricity than the polyurethane of the prior art and can be easily coated by electrostatic deposition.
