摘要：
By means of ultra-violet（UV）irradiation with photoini-tiator and multifunctional crosslinking agent,thecrosslinking modification of ultrahigh molecular weightpolyethylene（UHMWPE）fibers prepared by gel-spin-ning was carried out.Thermal properties of fiber sampleswere examined using differential scanning calorimetry（DSC）,thermomechanical analysis（TMA）apparatusand a manual device.The results indicated that the opti-mal irradiation energy is 250-400 mJ/cm;,heat-andcreep-resistant behaviors of modified fibers have beenimproved.
