ELASTOMER BASED ON LIQUID HYDROXYL-TERMINATED POLYBUTADIENE Ⅱ.INFLUENCE OF MOLECULAR WEIGHT DISTRIBUTION OF LIQUID HYDROXYL-TERMINATED POLYBUTADIENE ON THE MECHANICAL PROPERTIES OF ELASTOMER
Abstract:
The influence of molecular weight distribution of hydroxyl-terminated liquid polybutadiene(HTPB) on the mechanical properties of the elastomer obtained from HTPB, N, N-bis(2-hydroxypropyl) aniline and toluene diisocyanate has been investigated. The results showed that molecular weight distribution of HTPB had no marked effect on the tensile strength, 100% modulus and hardness of the elastomter. However, the permanent set of the elastomer increased obviously, when the polydispersity index of HTPB changed from 1.6 to 2.1.
