  In this note microgels with and without excluded volume interactions are
considered. Based on earlier exact computations on Gaussian mircogels, which
are formed by self-crosslinking (with $M$ crosslinks) of polymer chains with
chain length $N$ Flory type approximations are used to get first insight to
their behavior in solution. It is shown that two different types of microgels
exist: A special type of branched polymer whose size scales as $R \propto
N^{2/5} M^{-1/5}$, instead of $R \propto N^{1/2}$. The second type are $c^*$ -
microgels whose average mesh sizes $r$ are swollen and form self avoiding walks
with a scaling law of the form $r = a (N/M)^{3/5}$.
