Summary:
Iowa State University researchers have developed tackifiers from biorenewable sources that exhibit a maximum tack at approximately 80˚C.

Development Stage:
Description:
Tackifiers are important components of adhesive formulas, providing the stickiness or tack to the adhesive.  ISURF #04118 describes the initial synthesis of tackifiers from isosorbide and cyclic anhydrides to produce compounds with maximum tack between -20˚C to 40˚C (depending on the choice of anhydride).  ISURF #04346 builds upon this work by creating short oligomers of these tackifiers, resulting in maximum tack performance at 80˚C.

Group:
Advantage:
• Cost competitive with hydrocarbon-based resins; cost-advantaged versus other natural resins
• Bio-based with abundant supply of starting materials

Application:
Tackifiers for hot melt adhesives
