Abstract: | Mixing and curing experiments with suspensions of boron in hydroxyl-terminated polybutadiene (HTPB) have been performed. In kneading experiments on a plastograph very high viscous masses with bad curing properties were obtained. The experiments indicated that HTPB is attached with its OH groups to acidic impurities on the surface of the boron powder. By adding a basic substance, such as octadecyl amine, mixing and curing were undertaken with much less difficulty. |
