| Résumé : |
In recent years, more and more attention has been paid to green surfactants, which are safe, non toxic and environmentally friendly. In this paper the author present their research findings.
Acrylic polymer latex has been widely used in many fields, such as coatings, adhesives, textile, papermaking and leather industries because of its particular properties and environmental friendliness. Nonyphenol ethoxylates (NPEOs) are widely used as surfactants for emulsion polymerisation to stabilise the latex. However, NPEOs are bioaccumulative and persistant in the environment, while nonylphenol, the breakdown product of NPEs, is an endocrine disruptor. Therefore, the EU Commission has recommended implementing risk reduction strategy, which foresees the ban of all applications leading to direct emissions to waste water and strict emission controls for all other technical processes using NPEOs as surfactants. In one of the major fields of application, alkyl phenol-free surfactants, with a more favourable ecological profile, are becoming key ingredients for eco-friendly emulsion polymers and polymer dispersions. In this paper, different kinds of green surfactants in acrylic polymer latex were reviewed. |
