Abstract

Procedure for the manufacture of free flowing hollow pearls of thermoplastic synthetic materials, with an apparent density of 0.005 to 3.0 g/cc, a diameter from about 11 μ to 6 mm and a surface free of holes, characterized in that the pearls hollow, which have been mixed with 10 to 2,000% by weight of water, based on dry hollow beads, are mixed with 10 to 2,000 parts by weight, based on 100 parts by weight of dry hollow beads of a dissolved or dispersed adhesive in water, after which the pasty mixture is separated into a free-flowing mixture by the addition of at least one water-insoluble drying powder, employing 0.05 to 5.0 parts by volume of the powder per part by volume of beads dry hollows.
