Abstract
PURPOSE: To obtain a thermoplastic polyurethane resin having a high surface hardness, glass transition temperature and yield stress, by reacting a specific diol with a diisocyanate, etc. in a noncyclic ketone solvent.
CONSTITUTION: (A) A high-molecular weight diol having terminal hydroxyl groups and an average molecular weight of 500W5,000, e.g. polycaprolactone diol, is reacted with (B) neopentyl glycol and (C) diphenylmethane-4,4'-diisocyanate in (D) a noncyclic ketone solvent, e.g. methyl ethyl ketone, in the presence of (E) a reaction terminating agent, e.g. isopropanol, having one or more active hydroxyl groups at 50W90°C. The amount of the component (A) is 1W30wt% based on the total amount of the components (A), (B) and (C), and the ratio between the total number of hydroxyl groups in the components (A) and (B) and the number of isocyanate groups is 1/1.0W1/1.1.
