Block Copolymer EO-PO
Copolymer 4084 is a nonionic emulsifier for emulsion polymerization. This pale-yellow wax is composed of block copolymer of propylene oxide and ethylene oxide. Copolymer 4084 is used in emulsion polymerization of monomers like pure acrylic, styrene-acrylic acid esters and vinyl acetate, polyvinyl acetate, acrylate and styrene/acrylate dispersions to stabilize the rheological behavior of the polymer dispersions and to improve the electrolyte and shear stability. It can be used in combination with other nonionic, anionic and cationic surfactants. It is compatible with vinyl and acrylic resins. It reduces the amount of coagulum formed during the polymerization and improves the final latex property.
