What is chain length chemistry?

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.

How long is a 20 inch chain on a woman?

Chain Length A polymer with shorter chains will have more chain ends per unit volume, so there will be more free volume. Hence Tg‘ for shorter chains will be lower than Tg for long chains.
