Abstract

PARTICULATE SOLID 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 SIZING PROPERTIES EVEN ON PROLONGED STORAGE.
