THERMOSETTING POLYURETHANE ELASTOMER COMPOSITION, POLYURETHANE ELASTOMER AND PROCESS FOR PRODUCTION THEREOF |
摘要 |
<p>Provided is a polyurethane elastomer with a low hardness, a high strength and a high elongation. The polyurethane elastomer is obtained by reacting and curing an isocyanate-terminated prepolymer (i) obtained by reacting a polyoxyalkylene polyol having an average number of hydroxyl groups of over 2, a total degree of unsaturation of less than 0.05 meq/g and a number-average molecular weight of from 4000 to 20000, with a polyisocyanate compound, and a curing agent (ii) containing as curing components a polyoxytetramethylene polyol (a) and a chain extender (b) having two active-hydrogen-containing groups and having a number-average molecular weight of not more than 500.</p> |
