Synthesis of Comb-Like Copolymer Dispersant for Dispersing CaCO3 in Organic Medium

  • 摘要: 设计合成了一种新型梳型聚合物SMA-g-PSHD,用于在有机介质中分散超细碳酸钙。该梳型聚合物分别以羧基为锚固基团,低极性聚酯PSHD为溶剂化链。通过FT-IR、1H-NMR和凝胶渗透色谱(GPC)对梳型聚合物的结构、组成和分子量进行表征,并且系统地研究了SMA-g-PSHD对CaCO3在有机介质中的分散性、悬浮液流变行为和稳定性的影响,结果表明:梳型聚合物明显改善了CaCO3的分散性,使其在有机介质中几乎呈单颗粒分布;悬浮液黏度显著降低,并且呈近牛顿流体特征;SMA-g-PSHD改性后的悬浮液具有极佳的稳定性。
