| titleOfInvention | Process for producing fluoroelastomer |
| abstract | A process for producing a fluoroelastomer composed of vinylidene fluoride units and other fluoromonomer units copolymerizable therewith by suspension polymerization, which comprises: (1) dispersing the above monomers in 100 parts by weight of an aqueous medium containing 0.001-3 parts by weight of a suspension stabilizer, (2) using a polymerization initiator solution prepared by diluting 0.001-5 parts by weight of an oil-soluble organic peroxide in a concentration of 0.1-75 % by weight with a halogen-fee water-soluble hydrocarbon solvent represented by the general formula R-OH, R₂-COO-R₁ or R₁-CO-R₃ (wherein R₁ and R₃ represent each methyl or tert-butyl, and R₂ represents hydrogen, methyl or tert-butyl), and (3) conducting the suspension polymerization at 45-70 °C. The process provides a fluoroelastomer which has excellent resistances to heat, oil and chemical, a reduced compression set and a good releasability, and little stains a mold. Further it can dispense with the use of an ozonosphere-depleting chlorofluorocarbon solvent and facilitates the recovery of the monomers and solvent. |
