Claims14
A method for producing poly(acrylonitrile) homo- or co-polymers by RAFT polymerisation, the method comprising polymerising acrylonitrile and optionally one or more ethylenically unsaturated co-monomers under the control of a RAFT agent, wherein (i) the mole ratio of the polymerisable monomers to the RAFT agent is at least 4,000, and (ii) the mole ratio of the RAFT agent to initiator compound is no more than 3.
