【摘要】 胺中丙烯酸共聚物在水/助溶剂中的溶解性随着共聚物组成中丙烯酸含量的改变而变化。当共聚物中丙烯酸的含量从10mol%增加到50mol%时,共聚物—水/助溶剂体系的粘度—浓度曲线从“N”形经“反 S”形过渡到直线形。这一变化和溶液形态的研究结果表明,胺中和丙烯酸共聚物在水/助溶剂中是可以溶解的,并且其溶解性随着共聚物中羧基含量的增加而提高。更多还原

【Abstract】 The solubility of amine neutralized acrylic copolymcr in water-cosolvcnt mixture varies with the acrylic acid(AA)content of the copolymer.As it increases from 10 mole% to 50 mole%,the viscosity concontrastion curve progressively changes from an“N”shape,to a reversed“S”shape,and finally approaches a linear plot.This change and microscopic observations indicate that the amine neutralized acrylic copolymer is soluble in water-cosolvent mixture,and the solubility increases with increasing amounts of hydrophilic groups in the copolymer更多还原
