  A macromolecular emulsifier with switchable surface activity, and use thereof for preparation of polymer latex is disclosed. By using the macromolecular emulsifier with switchable surface activity as an emulsifier, a reversibly coagulable and re-dispersible polymer latex can be prepared by emulsion polymerization. The polymer latex can achieve the coagulation of latex particles by heating and aerating with nitrogen, air, inert gas and/or adding a small amount of alkali solution; the coagulated latex particles can be restored and re-dispersed into stable latex by aerating with carbon dioxide and/or adding a small amount of acid solution. The coagulation and re-dispersion process is reversible and is easy to control.

  本发明涉及一种具有可切换表面活性的高分子乳化剂，以及其用于制备聚合物乳液。通过使用具有可切换表面活性的高分子乳化剂作为乳化剂，可以通过乳液聚合制备可逆凝固和可再分散的聚合物乳液。该聚合物乳液可以通过加热和通入氮气、空气、惰性气体和/或添加少量碱溶液来实现乳胶颗粒的凝固；通过通入二氧化碳和/或添加少量酸溶液来恢复和重新分散凝固的乳胶颗粒为稳定的乳液。凝固和重新分散过程是可逆的，并且易于控制。
