Abstract
A process for the production of high compressive strength microspheres of cured phenolic resins are disclosed. Specifically, the microspheres formed by this process exhibit excellent viscoelastic properties in that the microspheres retain their shape even after applying a load of at least 4 GPa at 2.5 percent strain, and exhibit high hardness of at least about 0.3 GPa.
