Abstract
A polyurethane adhesive composition for carbon emission reduction, and a method of preparing same, includes polyether polyol containing a carbonate linkage, thus exhibiting a carbon emission reduction effect and good or desirable adhesion performance. The polyurethane adhesive composition is obtained by mixing a polyol mixture including polyether polyol containing a carbonate linkage and polytetramethylene glycol with an isocyanate in appropriate amounts and allowing the resulting mixture to react.
