ORGANIC PHOSPHITES RESISTANT TO HYDROLYSIS, AND PROCESS FOR PREPARING THEM

摘要

1. CASE 2459 "ORGANIC PHOSPHITES RESISTANT TO HYDROLYSIS, AND PROCESS FOR PREPARING THEM" 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.
