| titleOfInvention | Process for producing fluoropolymer |
| abstract | The present invention provides a process for preparing anfluorine-containing polymer having few branched chains and littlenweight change in high temperatures, which is a new process whereinncomposition distribution substantially does not occur. The fluorine-containingnpolymer is prepared by a batch copolymerization processnconducted under conditions of reduced temperature of at least 0.95 andnreduced pressure of at least 0.80 of the critical constant calculated fromncritical temperature, critical pressure and composition ratio of eachnmonomer in the gaseous phase of the reaction vessel using the Peng-Robinsonnformula; wherein when the number of monomer componentsnin the target polymer is represented as n (n is an integer of 2 or larger),nthe name of each monomer component is represented as A 1 , A 2 , ...A n ,nthe weight percentage of each monomer component A 1 , A 2 , ...A n of thentarget polymer composition is represented as a 1 , a 2 , ...a n (%) (a satisfiesn a n = 100), the weight percentage of each monomer component of theninitial monomer composition is represented as a' 1 , a' 2 , ...a' n (%) (a'nsatisfies a n ' = 100 and a' 1 , a' 2 , ...a' n is determined in a constantnmanner depending on predetermined polymerization conditions) andnspecific gravity of the gaseous phase monomers whennpolymerizing/ specific gravity of the target polymer is represented as B,nthe composition weight ratio of additional monomers is calculated forneach monomer from the formulan (a 1 -a' 1 × B) : (a 2 -a' 2 × B)...(a n -a' n × B) nin the order of components A 1 , A 2 , ...A n , and additional monomersncontaining additional monomers in the composition weight ratio ofnadditional monomers are added. |
