摘要：
Several urethane elastomers based on poly(oxytetramethylene glycol), butanediol 1,4 and various mixtures of 2,4 and 2,6 toluene diisocyanates were prepared. The tensile strength, moduli, glass transition temperatures, flow temperatures and relaxation properties were measured. These properties are discussed with reference to changes in microphase separation. Copyright © 1990 John Wiley & Sons, Inc.
