Abstract
One aspect of the present invention relates to a method for producing a hot-melt adhesive, comprising: introducing a fluid into a heating kneader while or after kneading a hot-melt adhesive material in a liquid state, at an amount of 0.3 parts by mass or more with respect to 100 parts by mass of the hot-melt adhesive material; and performing vacuuming while heating stirring or dispersing the hot-melt adhesive material and the fluid so as to come into contact with each other.

A method for producing a hot-melt adhesive, comprising:
- introducing a fluid into a heating kneader while or after kneading a hot-melt adhesive material in a liquid state, at an amount of 0.3 parts by mass or more with respect to 100 parts by mass of the hot-melt adhesive material;
- and
- performing vacuuming while heating, stirring, or dispersing the hot-melt adhesive material and the fluid so as to come into contact with each other to remove refractory organic compounds contained in the hot-melt adhesive material, which are adsorbed by the fluid, along with the fluid from the hot-melt adhesive material.
