摘　　要：Temperature sensitive poly(N vinylcaprolactam) was prepared by γ radiation polymerization.The effects of radiation dosage,radiation dose rate and monomer concentration on polymerization and the LCST characterisitcs of the polymer were studied.The results show that the polymer thus obtained has good temperature sensitivity and uniformity within certain radiation dosage range(1.4～4kGy) and dose rate range (2～14Gy/min).Temperature sensitive poly(N vinylcaprolactam) was prepared by γ radiation polymerization.The effects of radiation dosage,radiation dose rate and monomer concentration on polymerization and the LCST characterisitcs of the polymer were studied.The results show that the polymer thus obtained has good temperature sensitivity and uniformity within certain radiation dosage range(1.4～4kGy) and dose rate range (2～14Gy/min).
