New Generation of Green Nonionic Surfactants for Emulsion Polymerization

摘要

Alkyl phenol-free emulsifiers are key ingredients for eco-friendly emulsion polymers and polymer dispersions. The topic of this presentation is a new generation of green non-ionic surfactants, which are effective replacements for alkyl phenol and synthetic alcohol ethoxylates. The new non-ionic surfactants called Disponil? AFX, exhibit effective performance during polymerization and as post reaction stabilizers. They are environmentally compatible, mostly derived from natural renewable resources, readily biodegradable and FDA compliant. Clear, high solid liquids at room temperature, these surfactants are easy to handle and very effective at controlling particle size, film properties and overall latex stability. This presentation will be centered on their chemical and surface properties, as well as their performance in model emulsion polymerization formulations for architectural coatings.
