Investigation of the effect of electron radiation on selected mechanical properties of polylactide/polycaprolactone blends containing triallyl isocyanurate was the objective of the present paper. It was found that triallyl isocyanurate is an effective agent that hinders phase separation and links macromolecules of both the same and the different polymers. As a consequence of this, strength and modulus of elasticity of studied blends rise, while elongation at break as well as impact strength decrease. Moreover, some mechanical properties of crosslinked polylactide/polycaprolactone blends may also result from the partial degradation of polylactide phase after irradiation. (C) 2016 Elsevier B.V.
