Recently it has been shown that a two-dimensional model of self-attracting polymers based on attracting segments displays two phase transitions, a theta-like collapse between swollen polymers and a globular state and another between the globular state and a polymer crystal on the other hand. the canonical model based oil attracting monomers oil lattice sites displays only one, the standard tricritical theta collapse transition Here we consider rile attracting segment model with the addition of stiffness and show that it displays the same phases as the canonical model.
