The radiation crosslinking of polybutylene glycol terephthalate(PBT) was studied under various condition. It obeys Charlesby-Pinner equation. The dose for incipient gel formation are 62.5×10,4,Gy and 3.57×10,4,Gy at room temperature and fusion temperature respectively.,The structures and properties of croosslinked PBT were studied by DSC and MS methods. The results indicate that PBT is a radiation resistant polymer material, and some of the mechanical properties of PBT may be improved by radiation crosslinking.
