Abstract

PURPOSE: To prepare the titled resin having high Young's modulus and soluble in a ketone solvent or in a mixture of ketone and an aromatic hudrocarbon, by reacting a specific polymeric diol, a low-molecular diol, an organic diisocyanate and a reaction terminator using an organic solvent.
CONSTITUTION: The objective resin is prepared by reacting (A) a polymeric diol having an average molecular weight of 500W5,000, (B) a low-molecular diol having an average molecular weight of ≤, and (C) an organic diisocyanate in (D) a solvent such as methyl isobutyl ketone, and adding (E) a reaction terminator having one or more active hydrogen atoms such as isopropanol to the reaction mixture. The amount of the component (A) is 1W30(wt)% of the sum of the components (A), (B) and (C), and the ratio of the total number of OH groups in the component (A) and the component (B) to the number of isocyanate groups in the component (C) is adjusted to 1/(1.0W1.1).
