Gongye shui chuli, 2015 羧酸系阻垢剂具有对水环境无磷污染优势。通过实验对新型聚醚型羧酸系共聚物马来酸酐-烯丙氧基聚乙烯氧基羧酸钠(MA-APEC)、丙烯酸-烯丙氧基聚乙烯氧基羧酸钠(AA-APEC)及羧酸系聚合物水解聚马来酸酐、聚丙烯酸、丙烯酸/丙烯酸羟丙酯的阻磷酸钙垢能力进行了对比研究。实验结果显示, 5种阻垢剂均可使磷酸钙晶体形貌发生改变, 但拥有强亲水性聚乙烯氧基链段的聚合物MA-APEC和AA-APEC具有更优异的阻磷酸钙垢能力。

Effect of tacticity on intrinsic viscosity of polymer chain(PMA链规整性对溶液特性粘度的影响)
Zhejiang Daxue xuebao. Lixue ban, 2000 本文在旋转异构态模型下，导出高分子链构型参数理论公式，计算了聚丙烯酸甲酯链的特征比随分子量和链规整性变化的规律.并通过比较聚丙烯酸甲酯、聚苯乙烯和聚甲基丙烯酸甲酯链的计算结果，研究了溶液特性粘度与链规整性之间的关系.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Thermo‐responsive hydrogels based on poly(N‐isopropylacrylamide) (PNIPAM) are promising candidates for soft actuation, yet their practical applications are often constrained by sluggish thermo‐responsive kinetics and insufficient mechanical robustness.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous vanadium dioxide (VO2)‐based smart thermal insulation coatings represent a viable strategy to decrease building energy consumption and advance sustainable development goals. However, the inherent instability and limited compatibility with polymer matrices of VO2 hinder its widespread application.

Gongye shui chuli, 1989 作者用鼓泡法对丙烯酸的均聚物和共聚物,以及不同分子量的均聚物对碳酸钙的阻垢作用进行了对比研究。结果发现:(1)丙烯酸的均聚物和共聚物不仅有分散作用,而且还有阻垢(增溶)作用。(2)鼓泡法不仅可研究含磷阻垢剂,而且还可研究聚羧酸盐分散剂的阻垢作用。(3)丙烯酸共聚物的阻垢性能优于其均聚物。(4)西烯酸均聚物分子量在4000左右时的阻垢性能较好。
