    Abstract: A process including the steps of: providing a planetary roller extruder having a plurality of compounding sections including a main spindle surrounded by and intermeshed with a plurality of planetary spindles; introducing monomers and initiator into a first compounding section; producing a homogeneous composition; heating the composition to initiate free-radical polymerization; introducing monomers and initiator into one or more of the remaining compounding sections and continuing the polymerization; discharging the polymerized composition; and optionally, taking a portion of the composition discharged from the planetary roller extruder and returning it to the first compounding section.
