| Outline of Final Research Achievements |
Recently, we reported the transformation of chrysotile asbestos into a silicon polymer through several steps including acid leaching and silylation reaction. This method should be a potential method for the disposal and utilization of hazardous chrysotile asbestos as a nontoxic and valuable material.
The polymer obtained by this process has a silicone polymer main chain with reactive silanol groups, which can be easily transferred to various functional groups using silylation reagents. In this study, investigations on the transformation of silica into the polymer in a highly controlled manner, and application of the produced polymers having the reactive silanol residue, as well as the functional groups, as a novel additive to polyurethane and adhesives, were carried out. Consequently, the structure of the prepared silicone polymers significantly affected on the mechanical properties of the polyurethane (PU) films and adhesives.
