A generalization of the Eden model is proposed as a model of polymer c
rystallization. The model exhibits all three growth regimes. It produc
es the Seto-Frank model in one limit and demonstrates departures from
the Seto-Frank model induced by discreteness of the crystal. It is abl
e to predict curved growth fronts; in fact it predicts that circular c
rystals are to be expected in regime III.
