【摘要】 本文研究了聚丙烯酸钠的防垢效果与其分子量的关系,发现防垢率随其分子量的降低而增加。合成了不同组成的丙烯酸钠-醋酸乙烯酯无规共聚物,并对其作了表征,给出了奇特的NMR谱。实验结果表明,所合成的NaA-VAc无规共聚物型双亲聚合物水溶性好,且具有优秀的防垢性能。更多还原

【Abstract】 The relationship of scale-inhibiting effect and molecular weight of poly (sodium aery-late) was investigated. It was found that the inhibition of poly (sodium acrylate) increases with the decrease of its molecular weight. Sodium acrylate-vinyl acetate random copolymers with different composition were synthesized and characterized, and the peculiar NMR spectra were presented. The experimental results indicated that the NaA-VAc random copolymer-type am philic polymers were water-soluble and had excellent scale-inhibiting property.更多还原
