Basic Laboratory Polymerization Reactor Design

Some key features of a laboratory polymerization system designed for the preparation of approximately 50-100 g of polyethylene are as follows Location The complete polymerization system should be constructed in a walk-in type hood with a very good ventilation system. All glass reservoirs that contain liquids that will be transferred to the polymerization reactor need to be located within the hood. [Pg.368]

Reactor A stainless steel autoclave with a reactor diameter of about 20 cm is recommended for easy cleaning, with a total capacity of 1.0-2.0 [Pg.368]

If a cocatalyst such as an aluminum alkyl is required in the experiment, this reagent may be added to the reactor through an addition port that is fitted with a ballvalve and under a slow nitrogen purge. The aluminum alkyl may be added through the addition port using a syringe.The addition port may then be rinsed with a small quantity (5-10 ml) of heptane, and then the ballvalve is closed. [Pg.369]

Catalyst Addition Process It is highly recommended that the catalyst xmder investigation is added to the polymerization reactor while the reactor is xmder the steady-state conditions for any particular experiment. Consequently, the last step reqxiired once the reactor has reached the necessary polymerization conditions is the injection of the soUd catalyst into the reactor. [Pg.370]

In order to eliminate nonsteady-state polymerization conditions, the max-imxxm polymerization rate should not exceed about 1-2 g/minute/liter of [Pg.370]
