We have verified the detection response for heavy ions and radiation induced bond breaking in the CR-39 polymer and other polymers with very similar structure for understanding the track formation mechanism in CR-39 plastic nuclear track detectors. We have fabricated 4 types polymers with different chain length. The basic performance such as etching properties, etch pit detection under the microscope and track formation sensitivity for various heavy ions has been carried out in HIMAC heavy ion accelerator. We have confirmed that these new polymers operate as nuclear track etch detectors. We have also measured the variation of infrared absorption spectra of polymers before and after the beam irradiation. The identification of C=O and C-O-C peaks and comparison among polymers have been successfully achieved.
