Abstract

PURPOSE: To form a polyurethane elastomer having good dyeability and excellent weather resistance, by employing a combination of a specified polyhydroxy compound and a specified organic diisocyanate.
CONSTITUTION: A hydroxyl group-terminated polycaprolactone-amide ester (polyhydroxy compound), MW400W4,000, is reacted with an organic diisocyanate component consisting of at least one member selected from aliphatic, alicyclic and aralkyl diisocyanate (e.g., ethylene diisocyanate or xylylene diisocyanate) at about 60W120°C for 2W6hr. Then, a polyurethane elastomer is formed by chain- extending the above-produced prepolymer having isocyanato groups on both molecular terminals by reacting the prepolymer with a low-molecular diol (e.g., ethylene glycol) or a low-molecular diamine compound (e.g., ethylenediamine).
