Abstract

We studied the properties of simple models of linear and star-branched
polymer

chains confined in a slit. The polymer chains were built of united
atoms and were

restricted to a simple cubic lattice. Two macromolecular architectures
of the chain: linear

and star-branched with three branches (of equal length) were studied.
The excluded

volume was the only potential introduced into the model and thus,
the system was

athermal. The chains were put between two parallel and impenetrable
surfaces. Monte

Carlo simulations with a sampling algorithm based on chain's local
changes of conformation

were carried out. The differences and similarities in the global size
and the

structure and of linear and star-branched chains were shown and discussed
