PROCESS FOR THE PREPARATION OF SILICONE POLYMER/SOLID PREMIXES HAVING A HIGH FILLER CONTENT

摘要

A silicone polymer/solid premix may be prepared by incorporating into (A) a mixturecomprising (a) 50 to 100 parts by weight of at least one polyorganosiloxane containing up to5 mol % of crosslinkable groups, and (b) 5 to 200 parts by weight of at least one readilyvolatile organosilicon compound containing no hydrolyzable groups, 100 to 500 parts byweight of (B) a solid, thereby forming a composition; removing (b) said organosiliconcompound (b) from said composition; and then subjecting said composition to mechanicalstress.
