摘　　要：利用硝酸稀土作为改性剂,加入到聚氯乙烯(PVC)的四氢呋喃(THF)溶液中,用流延法制得表观透明均匀的PVC膜。经紫外辐射交联后,测试其力学和物理性能。发现经稀土改性后的PVC薄膜的力学和物理性能均有了较大的提高。The transparent PVC films were prepared by doctorblade casting. In the course of preparation, rare earth nitrates, as modifying agents, were added to the solution of PVC and THF. These PVC films were tested after being crosslinked by ultraviolet light. It was found that the mechanical and physical properties of the PVC films modified by rare earth nitrates all were greatly enhanced.
