Outline of Final Research Achievements

We examined the core-shell microspheres composed of polybutadiene (PBD, syndiotactic 1,2-polybutadiene (SPBD) and cis and trans 1,4-polybutadiene (CPBD) ) and ceramic materials were prepared, with a control of facial and elastic property, in order to develop the elastic blasting materials. The PBD microsphers were obtained using suspension evaporation method. The typical spherical particulates were obtained. On the other hand, the surface-modification on the ceramic materials, i.e. Al2O3 particles, was performed using (3-mercaptopropyl) trimethoxysilane (MPS). Immobilization of MPS-ceramic materials on surface of SPBD/CPBD microsphere were carried out by the ene-thiol reaction between double bonds in SPBD and SH groups in MPS-modified ceramic particles. As a result, the surface of microsphere could be covered with ceramic particles. In addition, we confirmed that the elasticity of microspheres could be controlled by the addition of CPBD to SPBD.
