  The dynamical systems methods are used to study evolution of the polymerised
scalar field cosmologies with the cosmological constant. We have found all
evolutional paths admissible for all initial conditions on the two-dimensional
phase space. We have shown that the cyclic solutions are generic. The exact
solution for polymerised cosmology is also obtained. Two basic cases are
investigated, the polymerised scalar field and the polymerised gravitational
and scalar field part. In the former the division on the cyclic and non-cyclic
behaviour is established following the sign of the cosmological constant. The
value of the cosmological constant is upper bounded purely from the dynamical
setting.
