ABSTRACT:
A pressure-sensitive adhesive composition with a low content of volatile liquids, such as organic solvents or water, comprises a maleinized liquid polybutadiene blended with one or more tackifying resins and one or more curing agents, suchas a blocked polyamine, the composition containing less than 20% by weight of volatile liquids. The liquid polybutadiene, which can be made by any conventional polymerization mechanism, is maleinized by reaction with meleic anhydride, and it is convenient to add the tackifying resin and any other ingredients of the composition to the maleinized liquid polybutadiene just after the maleinization reaction.
