RELATIONS BETWEEN INSTANTANEOUS AND CUMULATIVE AVERAGE CHAIN LENGTHS... [Pg.169]

Given any instantaneous or cumulative average chain length as a function of conversion in a batch reactor, the others may be calculated as follows. Recall that conversion is defined as... [Pg.169]

FIGURE 9.5 Instantaneous and cumulative number-average chain lengths versus conversion for an isothermal, free-radical, batch polymerization (data of Example 9.10). [Pg.168]

Also keep in mind that if samples are removed from the reactor and analyzed for number-average chain length, the quantity determined is . The cumulative quantity is what characterizes the reactor contents. The only way to measure would be to sample at a very low conversion, where . [Pg.169]

In addition to the instantaneous copolymer composition another quantity of interest is (F/), the cumulative composition of the copolymer that has been formed up to a particular conversion. Fj) is exactly analogous to (x ), the cumulative number-average chain length from Chapter 9. For a batch reactor, it is obtained through a material balance ... [Pg.213]
