摘要：
Solid organic phosphites in powder form, used to endow organic polymers with stability characteristics are made resistant to hydrolysis by treating said powder phosphites with a silane containing in its molecule at least two alkoxy groups and causing the silane to hydrolyze, and the formation and deposition of a siliconic polymer on the surface of powder particles to occur.
