| Outline of Final Research Achievements |
Microscopic structures that emerge from the gas-liquid interface of single rising bubbles a hydrophobically modified alkali-soluble emulsion polymer (HASE) solution are experimentally examined. It is shown that microscopic structures can be emerged when primal-TT935 solutions are used. The state of microscopic structures that emerge from the gas-liquid interface depends on rheological properties and bubble size. From consideration of the effect of alkaline substances, it can be expected that primal-TT935 solutions become transparent and have the characteristic elastic effect when alkaline substances have the sodium atom.
