how can you calculate average of various chain structure explain
Answers
Answer:
Experimentally this is determined via some combination of light scattering, viscometry, and size exclusion chromatography. Theoretically for a controlled radical polymerization this number is just the molar ratio of monomer to initiator. For an uncontrolled radical polymerization, which seems to be what you are describing, you can calculate this using what is called the kinetic chain length. This is just the average length a chain will grow to before terminating, and depends on the rates of chain growth and chain termination. These numbers must be measured though, its almost always easier to just measure the molecular weight to get your kinetic chain length
Answer:
For any chemical chain reaction, the chain length is defined as the average number of times that the closed cycle of chain propagation steps is repeated. It is equal to the rate of the overall reaction divided by the rate of the initiation step in which the chain carriers are formed
