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.
Claims9
Apparatus for copolymerizing at least two gaseous monomers comprising:
- A. a closed reactor for receiving said monomers and subjecting them to copolymerizing conditions;
- B. at least three feed tanks for containing said monomers under pressure under conditions which preclude copolymerization;
- C. a first feed manifold connected to one end of each said tank and to said reactor;
- D. first valve means in said first feed manifold for controlling flow therein between the first and second of said feed tanks. for controlling flow therein between the second and third of said feed tanks and for controlling flow therein between said feed tanks and said reactor;
- E. a second feed manifold connected to the other end of each of said feed tanks and to said reactor;
- F. second valve means in said second feed manifold for controlling flow from each of said three feed tanks into said second feed manifold;
- and
- G. third valve means in said second feed manifold for controlling flow therein between said first and second tanks and for controlling flow therein between all said feed tanks and said reactor.
