Abstract
Monte Carlo simulation technique has been used to investigate the static properties and
translocation characteristics of ring polymers in two dimensions. Each chain consists of
exible
linkage between monomers forming a closed loop. We consider the unbiased translocation process
of the ring where the polymer translocates purely due to thermal
uctuations. The average escape
time has been analyzed as a function of chain length N. And we found that, the polymer escape
time of the ring polymers having a length N < 100, also has a scaling behavior N where
is more closer to 1 + 2 in which is the Flory exponent of value 3/4 in 2D and 3/5 in
3D. Such scaling is also the scaling behavior of the unbiased long linear chains. We study the
static property of the small cyclical polymer chains by calculating the mean-squared radius of
gyration Rg. Bond
uctuation method (BFM) is implemented to study both characteristics of
the particular ring polymers
