ABSTRACT:
Apparatus for copolymerizing at least two gaseous monomers to form block copolymers or gradient copolymers comprising a closed reactor for receiving the monomers and subjecting them to copolymerizing conditions, at least three feed tanks for containing the monomers under pressure, a first feed manifold connecting one end of each feed tank to the reactor, first valve means in the first manifold for controlling flow therein between the first and second feed tank, between the second and third feed tank and between the feed tanks and the reactor, a second feed manifold connecting the other end of each feed tank to the reactor, and second valve means in the second manifold for controlling flow from each feed tank into the second manifold.
