Temperature measurement of a biodegradable plastic made from oil was made using thermocouples during dynamic compression. The relationship between strain rate and temperature rise was examined at a strain rate from 300 s^<-1> to 900 s^<-1> using a split Hopkinson pressure bar (SHPB) system. Immediately after the onset of compressive loading, the temperature started to increase and the temperature histories showed a peak after the compressive loading finished. However, compared to metals, the temperature rise was not large. The temperature, the plastic work and the ratio of the temperature rise to the plastic work increased as increasing strain rate.
