We solve models of self- and mutually avoiding M-mers placed on the Be
the lattice with additional energies that include (i) semiflexibility
of the chains, (ii) attractive interactions between first neighbors, a
nd (iii) preference for spatial orientation of bonds on the lattice. F
ree energies and phase diagrams are obtained and compared to earlier r
esults when available. For the case of polymers on an anisotropic Beth
e lattice with a coordination number equal to 4, we find two different
polymerized phases.
