Method of preparing homogeneous compositions in the form of thermoplastic polymer particles specially adapted to be used in the preparation of adhesive substances fusible at elevated temperatures

摘要

A method of making homogeneous particulate compositions for use as heat-fusible adhesives which include a thermoplastic polymer and a gluing agent. The method includes the steps of preparing a mixture of water, the gluing agent, and a suspension agent, heating the mixture to the fusing temperature of the polymer, stirring in such a way that the molten mass is broken up into particles of about 0.005 to about 5 mm, cooling while stirring, and separating the particles from the aqueous phase.
