Abstract: The present invention relates to a linear polyureaurethane polymer, produced without the use of any chain extender. The hard block of the resulting polymer thus consists of diisocyante groups linked to each other via without the presence of any chain extender component. The hard block of the polyureaurethane material is preferably synthesized by using diisocyante groups in the form of lysine diisocyanate (LDI). The soft block component of the polyureaurethane material is preferably poly(epsilon-caprolactone) (PCL). The invention also relates to a method of producing a polyureaurethane polymer, which in short comprises the steps of reacting a soft block component with a diisocyante group in order to prepare a prepolymer component, combining the prepolymer component with a catalyst in order to define a reaction solution and adding water to the reaction solution, preferably carried to the reaction solution in vapour phase.
