Abstract
A system for making sheets, films, and objects including a reactor-dryer for reacting at least one monomer to produce a polymer melt; a flash melter in communication with the reactor-dryer for heating the polymer melt received from the reactor-dryer; a flash tank in communication with the flash melter for removing volatile compounds from the polymer melt; and a control loop in communication with the flash tank for controlling the pressure of the polymer melt from the flash tank to a die forming unit. Methods of making sheets, films, and objects is further included.

A method for making sheets, films, and objects directly from a polymerization reaction, comprising:
- reacting at least one monomer to produce a polymer melt;
- flowing the polymer melt to a valve having at least two outlets;
- flowing the polymer melt from at least one of the at least two outlets to at least one distribution manifold, each of the at least one distribution manifold having at least two distribution lines;
- controlling individually the mass flow of the polymer melt in each of the at least two distribution lines independently of the other of the at least two distribution lines;
- and
- forming the sheets, films, and objects from the polymer melt.
A method for making multi-layer sheets or objects, comprising:
- reacting at least one monomer a polymer melt;
- removing volatile compounds from the polymer melt;
- controlling the flow of the polymer melt to a valve having at least two outlets to produce a first polymer melt stream and a second polymer melt stream;
- controlling the flow of the first polymer melt stream to a die forming unit;
- mixing an additive to the second polymer melt stream;
- controlling the flow of the second polymer melt stream to the die forming unit;
- and
- forming the multi-layer sheets, films, and objects from the first and second polymer melt streams.
A system for making sheets, films, and objects comprising:
- a reactor-dryer for reacting at least one monomer to produce a polymer melt;
- a flash melter in communication with the reactor-dryer for heating the polymer melt received from the reactor-dryer;
- a flash tank in communication with the flash melter for removing volatile compounds from the polymer melt;
- and
- a control loop in communication with the flash tank for controlling the pressure of the polymer melt from the flash tank to a die forming unit.
A system for making multi-layer sheets, films, and objects, comprising:
- means for reacting at least one monomer a polymer melt;
- means for removing volatile compounds from the polymer melt;
- means for controlling the flow of the polymer melt to a valve having at least two outlets to produce a first polymer melt stream and a second polymer melt stream;
- means for controlling the flow of the first polymer melt stream to a die forming unit;
- means for mixing an additive to the second polymer melt stream;
- means for controlling the flow of the second polymer melt stream to the die forming unit;
- and
- means for forming the multi-layer sheets, films, and objects from the first and second polymer melt streams.
