Abstract
Products of a generally spherical nature with particulate matter embedded in the walls are prepared by forming a suspension of said particulate matter in a solution of a film-forming substance in a volatile solvent, spray drying said suspension-solution thereby forming the product which may be further dried if necessary to remove solvent and to 'set' the walls. Such products can be used to provide pigmenting, reactive and/or fire retardant properties to organic systems to which they are added as fillers. The density of the product can also be controlled by this method for use as fillers in applications in which segregation of such fillers from the plastic matrix is normally a problem.
