METHOD FOR PRODUCING PRESSURE-SENSITIVE ADHESIVE RESIN PELLET AND METHOD FOR PRODUCING HOT-MELT PRESSURE- SENSITIVE ADHESIVE PELLET

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a pressure-sensitive adhesive resin pellet capable of surely preventing occurrence of blocking not only immediately after production but also in the case of long-term preservation. SOLUTION: This method for producing a pressure-sensitive adhesive resin pellet comprises melting a pressure-sensitive adhesive resin 1, leading the molten resin to a thin hole 3a at a fixed velocity to form the pressure-sensitive adhesive resin, then cutting the formed resin in water 4 containing a self-adhesion preventing substance (preferably talc, silica, etc.), bringing cut pieces, namely pellets 6 of the pressure-sensitive adhesion resin into contact with water containing the self-adhesion preventing substance for a fixed time and drying the pellets.
