METHOD FOR MANUFACTURING AQUEOUS-DISPERSION COMPOSITION OF COUMARONE-INDENE RESIN, AND SAID AQUEOUS-DISPERSION COMPOSITION

摘要

As a manufacturing method of a stable coumarone-indene resin water-dispersed composition which does not use an organic solvent, can be applied to various resin compositions, enhance sticky and adhesive properties, water resistance, heat resistance, and compatibility, and achieve consideration of health and safety of operators, arrangement of a work environment, and cost reduction relating to exhaust gas treatment, a manufacturing method which includes a process of dispersing a coumarone-indene resin which contains 50% by weight or more of coumarone and indene in total as monomer constituents and is in a solid form at an ordinary temperature in the presence of a surfactant by a wet milling and dispersing method is used.
