We show that percolation and structural arrest transitions coexist in different regions of the phase diagram of a copolymer-micellar system and relate them to short-range intermicellar attraction. The intermediate scattering function shows a nonergodic transition along a temperature and concentration dependent line. Analyses show a logarithmic time dependence, attributed to a higher-order glass transition singularity predicted by mode-coupling theory, followed by a power law.
我们表明，在共聚物-胶束体系的相图不同区域中，渗流和结构阻滞转变共存，并将它们与短程胶束间吸引力联系起来。中间散射函数沿温度和浓度依赖线显示出非遍历转变。分析表明存在对数时间依赖性，这归因于模式耦合理论预测的高阶玻璃转变奇异性，随后是幂律。
