概要
- 論文の詳細を見る
Partially sulfonated poly(1,4-piperazinediylterephthaloyl)(SPP) microcapsules were found to undergo disintegration by the action of dodecylpyridinium ions when the surfactant cation concentration exceeded a certain value which was dependent on pH of the medium. At their lower concentrations, dodecylpyridinium ions interacted with negatively charged SPP microcapsules to produce aggregation of the latter. A polyelectrolyte-type viscosity behavior was observed with the complex formed between SPP and dodecylpyridinium ions in the disintegration process of the microcapsules. Crosslinking of the terminal amino groups of SPP microcapsules prevented disintegration from taking place.
