End-group initiation first-order and disproportionation termination narrow distribution

4 End-group initiation first-order and disproportionation termination narrow distribution 

There is no decrease in the number of molecules since only the 

This solution does not hold for a wide distribution, since complete loss of the shorter molecules may occur even for low zip length and eqn. (47) is not valid. 

Rn molecules are rare and the last two terms of eqn. (16) disappear. Then 

The degree of polymerization x at time t is independent of the initial distribution in all cases since
