Process for forming a powdered EPDM terpolymer (C-955) |
摘要 |
A process for forming a powdered EPDM terpolymer, wherein the powder of said EPDM terpolymer has a volume density of about 10 to about 30 lb/ft3 which includes the steps of adding a cement of an EPDM terpolymer in a hydrocarbon solvent to water, a volume ratio of the water to the cement being about 60 to 1 to about 2 to 1; emulsify under high-shear the blend of the water and the cement thereby forming a dispersion of particles of the EPDM terpolymer in the water; steam stripping under high agitation the emulsified blend of the EPDM terpolymer, the water and the solvent thereby removing the solvent from the emulsified blend; filtering the dispersion of the particles of the EPDM terpolymer in the water to recover a wet powder of the EPDM terpolymer; and hot-air drying the wet powder of the EPDM terpolymer in a fluid-bed dryer.
