Abstract
Carboxyl-terminated polybutadienes were ionically cross-linked by divalent metal oxide or monovalent metal hydroxide. The thermal, dynamic mechanical, and dielectrical behaviors of these ionomers were examined according to the ratio and the nature of the neutralizing agents. The variations of transition parameters and the classification of the different relaxations could be related to the degree of microphase separation between the elastomeric phase, the multiplet structure, and their associations in clusters.Keywords
