Vinylidene fluoride → HCID 131717214, compound

Participants

Reaction Steps

Carrier particles were prepared by coating 150 pounds of a Toniolo atomized steel core, 120 microns in diameter, with 0.45 pounds of polymethyl methacrylate, PMMA, available from Soken Chemical as MP116, and 0.45 pound of polyvinylindene fluoride, available as Kynar 301F. The core and PMMA are mixed first in a MX-1 Munson mixer for 10 minutes, the mixer is inactivated, the Kynar added and mixing continued for 20 more minutes. There results an electrostatically attached uniform distribution of the Kynar/PMMA on the carrier core as determined by visual observation. The resulting carrier particles were metered into a rotating tube furnace available from Harper Company at a rate of 400 grams/minute. This furnace was maintained at a temperature of 400° F. thereby causing the polymers to melt and fuse to the core.
