Block copolymer particle forming process
a process is provided for the formation of block copolymer particles having a reduced tendency to agglomerate which comprises extruding the block copolymer into a water bath in the presence of water-dispersible polyvalent metal salts of higher fatty acids and/or water-dispersible surfactants and forming nibs, pellets or strands in the bath. Suitable water soluble surfactants include anionic, cationic and non-ionic surfactants. Especially contemplated is the use of zinc stearate as the surfactant.
