METHOD OF PRODUCING PERFLUORINATED COPOLYMER WITH SULFO-GROUPS |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: method is realised via copolymerisation of tetrafluoroethylene (TFE) and perfluro(3,6-dioxy-4-methyl-7-octene)sulfonylfluoride (FS141) in a medium of organic solvent. Copolymerisation is carried out in a medium of solvent - 1,2-dichlorohexafluorocyclobutane (RC 316) at pressure 2.5-5 atm using bis(perfluorocyclohexanoyl)peroxide as an initiator. ^ EFFECT: low explosion hazard of the process and replacement of the ozone-decomposing solvent by an environmentally safe solvent. ^ 1 cl, 1 ex, 1 tbl |
