    • The invention relates to a latex composition wherein the latex composition comprises a butyl ionomer or partially halogenated butyl rubber ionomer. The latex composition is formed by dissolving the butyl ionomer in a suitable solvent, emulsifying the polymer in the solvent, adding water and optionally a minor amount of a suitable surfactant system to the emulsion and concentrating the emulsion to remove the water. The advantages of butyl ionomer latex include lower emulsifier levels, increased latex stability, improved interaction and adhesion to polar substrates and surfaces. Through the judicious choice of emulsifiers and/or washing to remove excess emulsifier a film with enhanced non-extractable polymeric antimicrobial function can be created. These properties of ionomer latex are useful in coatings, dipped goods and sponge applications.
    • 本发明涉及胶乳组合物,其中胶乳组合物包含丁基离聚物或部分卤化的丁基橡胶离聚物。 通过将丁基离聚物溶解在合适的溶剂中,将聚合物在溶剂中乳化,将水和任选的少量合适的表面活性剂体系加入到乳液中并浓缩乳液以除去水来形成胶乳组合物。 丁基离聚物胶乳的优点包括较低的乳化剂含量,增加的胶乳稳定性,改进的相互作用以及对极性基材和表面的粘附性。 通过明智地选择乳化剂和/或洗涤以除去过量的乳化剂,可以形成具有增强的不可萃​​取的聚合物抗微生物功能的膜。 这些离聚物胶乳的性能可用于涂料,浸渍物品和海绵应用。
