    摘要： The present invention provides a process for preparing a fluorine-containing polymer having few branched chains and little weight change in high temperatures, which is a new process wherein composition distribution substantially does not occur. The fluorine-containing polymer is prepared by a batch copolymerization process conducted under conditions of reduced temperature of at least 0.95 and reduced pressure of at least 0.80 of the critical constant calculated from critical temperature, critical pressure and composition ratio of each monomer in the gaseous phase of the reaction vessel using the Peng-Robinson formula.

An, the weight percentage of each monomer component A1, A2, . . . An of the target polymer composition is represented as a1, a2, . . . an (%) (a satisfies ∑ n ⁢ a n = 100 ) , the weight percentage of each monomer component of the initial monomer composition is represented as a′1, a′2 . . . a′n (%) (a′ satisfies ∑ n ⁢ a n ′ = 100 and a′1, a′2, . . . a′n is determined in a constant manner depending on predetermined polymerization conditions) and specific gravity of the gaseous phase monomers when polymerizing/specific gravity of the target polymer is represented as B, the composition weight ratio of additional monomers is calculated for each monomer from the formula (a1−a′1×B):(a2−a′2×B) . . . (an−a′n×B) in the order of components A1, A2, . . . An, and additional monomers containing additional monomers in the composition weight ratio of additional monomers are added.
