ABSTRACT:
The novel adhesives of this invention contain a blend of components that result in the adhesive having a physical property that changes at a controlled rate as a function of time after application until it reaches a final equilibrium value.
The adhesives can contain a thermoplastic polymer base, a tackifying resin, and an aromatic plasticizer optionally in combination with other ingredients. The plasticizer tackifier combination is chosen such that the tackifier/plasticizer interaction causes the initial value of the physical property after application to change, at a controlled rate, to a final equilibrium level.
