Claim:
1. A process for removing thiocarbonylthio groups from a polymer prepared by RAFT polymerisation, the process comprising: introducing into bundled flow lines or a coiled flow line of a tubular flow reactor a solution comprising a RAFT polymer in solvent; and promoting a reaction within the flow reactor that removes the thiocarbonylthio groups so as to form a solution that flows out of the reactor comprising the RAFT polymer absent the thiocarbonylthio groups, wherein the reaction within the flow reactor that removes the thiocarbonylthio groups is promoted by: (i) increasing the temperature of the solution comprising the RAFT polymer to remove the thiocarbonylthio groups by thermolysis; (ii) irradiating the solution comprising the RAFT polymer; or (iii) introducing a reagent into the solution comprising the RAFT polymer, wherein,
