Abstract
The polymerization of fluoromonomers can be accomplished without fouling by using gaseous monomers in the presence of at least one nonvolatile initiator and by recycling the initiator-free polymerizer gases through an external cooler.
Claims8
In a continuous, free-radical initiated process for preparing fluorinated polymers comprising polymerizing at least one gaseous fluoroolefin in a stirred polymerizer, the improvement consisting essentially of removing polymerization heat by recycling polymerizer gases through an external heat exchanger and the initiator used for polymerization is not capable of entering the recycle gas stream.
