Elastomers containing bismuth compounds protecting against X-rays
Natural rubber was filled with Bi(2)O(3), (BiO)(2)CO(3), BiOCl and BiVO4 (75-150%), vulcanized with S and ZnO at 150 degrees C and studied for swelling in PhMe, tensile strength and gamma irradn. absorbability (60 and 120 key). The highest gamma absorption was obsd. for Bi(2)O(3), BiOCl and (BiO)(2)CO(3)-contg. vulcanizates.
