The process including the steps of charging a polymerization reactor with deionized water and a stabilizer, raising the temperature to 50 to 120° C., feeding VDF to the reactor until the pressure reaches from 100 kPa to 10 MPa, adding an initiator to start the polymerization, continuously feeding VDF to maintain said pressure, and stopping the VDF feed when the desired amount of polymer conversion has been reached.
The production method comprises the steps of:
pyrolizing the feed material in a pyrolysis reactor so as to generate a gas stream, the feed material travelling from an inlet of the pyrolysis reactor to an outlet of the pyrolysis reactor with being subjected to heat such as to generate the gas stream at the outlet of the pyrolysis reactor; and
