All-polymer composites – a new approach with the use of disentangled semi-crystalline polymers. Part II. Preparation of composites from partially disentangled polylactide

Abstract

The mechanical properties of two uniaxially stretched polylactides have been studied: the polylactide with reduced density of entanglements of macromolecules and with equilibrium density of entanglements. It has been shown that plastic deformation is easier in a partially disentangled polymer. Thus, this polymer was used to form an all-polymer composite by blending it with a second molten polymer: poly(butylene succinate) or polystyrene. During mixing, polylactide fibers were produced that strengthened the prepared composite.
