Abstract

Oriented, amorphous poly(D,L-lactide) was obtained by drawing injection moulded specimens at temperatures below the glass transition temperature of the polymer and by a non-conventional injection moulding process in which the melt is cooled under oscillating shear conditions (SCORIM). In both cases effective molecular orientation is achieved, allowing the preparation of degradable devices with much improved tensile properties and impact behaviour when compared to the non-oriented material.
