FIELD: chemistry.
SUBSTANCE: invention relates to a partially fluorinated compound I (CF2)xCH=CH2, where x is 3, as well as the method for its preparation, comprising the reaction of a compound of the formula I (CF2)xI with ethylene to produce a compound of the formula I (CF2)xCH2CH2I and the dehydroiodination thereof to obtain the claimed compound (the value of x in these formulas is 3). The invention relates to a fluoropolymer for vulcanization comprising a polymerized reaction product of: (a) a partially fluorinated compound and (b) a fluorinated olefin monomer; to a rubber product for sealing moulded from a vulcanized fluoropolymer; to a process for producing a fluoropolymer, comprising: (a) providing a partially fluorinated compound, a fluorinated olefin monomer, and an initiator; and (b) polymerizing a partially fluorinated compound and a fluorinated olefin monomer to produce a fluoropolymer.
EFFECT: good physical properties, vulcanization properties and curing time, long-term stability.
