Positron lifetime measurements have been performed on differently manufactured PEEK samples of different molecular weights. Our measurements confirmed an old assumption: the o-Ps lifetime changes linearly with the molecular weight of the polymer. We have found that both the size of the free volumes and their number increase with increasing molecular weight of the investigated polymers.
