Abstract (en)
Particulate solids comprising ketene dimers may be obtained by drying a conventional aqueous dispersion of the dimer to which a water dispersable encapsulating agent has been added. Preferably the encapsulating agent is a cationic starch and the solid is obtained by spray drying the emulsion under controlled conditions. The products retain their sizing properties even on prolonged storage.
