Abstract

The polymerization kinetics of 50 volume percent suspensions of four oxide powders in isobornyl acrylate solutions initiated with benzoyl peroxide were determined with dynamic differential scanning calorimetry at a range of heating rates. Compared with the powder-free isobornyl acrylate solution, polymerization kinetics were similar for titania suspensions. Polymerization kinetics were much faster in suspensions of barium titanate, strontium titanate, and alumina powders, indicating a significant catalytic effect of the oxide surfaces.

氧化铝、二氧化钛和钛酸盐粉末的丙烯酸单体悬浮液的热聚合

用动态差示扫描量热法测定了四种氧化物粉末的50%体积悬浮液在不同升温速率下在丙烯酸异硼酸酯溶液中的聚合动力学。与无粉丙烯酸异硼酸酯溶液相比，二氧化钛悬浮液的聚合动力学相似。在钛酸钡、钛酸锶和氧化铝粉末的悬浮液中，聚合动力学要快得多，这表明氧化物表面具有显著的催化作用。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
