摘要：
Poly-lead acrylate was synthesized by azobisisobutyronitrile initiating the product of lead oxide and acrylic acid, and the poly-lead acrylate/ethylene-propylenediene rubber (EPDM) composites were prepared using peroxide as curing agent. The composites were characterized and analyzed by FT-IR, XRD, and SEM. Then the tensile strength and elongation at break were measured by universal testing machine, the hardness was tested by Shore hardness tester, and the shielding performance was measured by high purity germanium gamma spectrometer. The results show that the tensile strength and hardness of the composites are increased with increasing of the filler content, and the elongation at break is decreased with increasing of the filler content. The mass attenuation coefficient of the composites for γ-ray is improved with increasing of the filler content. © 2017, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
