一、前言人工肾以血液透析清除肾功能衰竭患者体内代谢废物,并保持水、电解质及酸碱平衡,代替了肾脏的部分功能。人工肾功能的好坏主要取决于透析膜,目前临床上用得较广泛的是铜玢膜;它对小分子量的代谢物透过性较好,对分子量范围在500～2000的中等分子量代谢物透过性较差,因此会引起患者特异的神经症状和色素沉淀症状。为了改善对中等分子量代谢物的透过性,许多国家的学者研究了各种合成高分子透析膜。本文以硝酸铈铵为引发剂,研制了聚乙烯醇接枝丙烯腈和甲基丙烯酸β-羟乙基酯的胶乳膜,测定了接枝膜对尿素、葡萄糖、磺
I. Introduction Artificial kidney hemodialysis patients with renal failure to remove metabolic waste, and maintain water, electrolyte and acid-base balance, replacing some of the kidney function. Artificial kidney function is mainly depends on the quality of dialysis membrane, currently widely used in clinical copper membrane; its small molecular weight metabolites better permeability, molecular weight range of 500 ~ 2000 in the middle-molecular weight metabolites Poor permeability, it will cause patients with specific neurological symptoms and pigmentation symptoms. In order to improve the permeability of metabolites of medium molecular weight, many countries have studied various synthetic polymer dialysis membranes. In this paper, ammonium vinyl nitrate as initiator, polyvinyl alcohol grafted acrylonitrile and β-hydroxyethyl methacrylate latex film was measured grafted film on urea, glucose, sulfonamide
