The trapped electrons or anions in molecular solids and polymers cause the enhancement of positronium formation at low temperatures during positron annihilation lifetime (PAL) measurement. This method can be applied to investigate trapped electrons and anions in polymers. The advantage of the method is that the any kinds of trapped electrons or anions can be observed. We clarified that the glow peak appeared around 240K was caused by the trapped electrons on -CH- radicals by PAL experiment.
