ABSTRACT:
Fluoropolymers are prepared by a process comprising polymerizing at least one fluoromonomer in an aqueous reaction medium containing monomer, a radical initiator and a 3-allyloxy-2-hydroxy-1-propanesulfonic acid salt as surfactant. The medium may optionally contain one or more of an antifoulant, a buffering agent and a chain-transfer agent.
