Conformation space renormalisation group theory is applied to study
the size distribution of living or self-assembling polymers in good solvents.
In dilute solution the aggregate size distribution is found to be of
the Schulz-Zimm type. It crosses over to
an (almost) exponential distribution in the
semi-dilute regime. The
growth exponent, describing the power law dependence of the mean aggregate size
on the concentration, changes from
in dilute to
in semi-dilute solution,
to
first order in
with
the dimensionality of space.
