Acrylic-based pressure sensitive adhesives are modified with a telechelic hydrocarbon oligomer. The oligomer comprises a hydrocarbon polymer chain or backbone and a functional end group, e.g., an oligomer prepared from a mono hydroxyl polybutadiene polymer and toluene diisocyanate. The oligomer attaches to the acrylic backbone of the polymer as a pendant group and in a preferred embodiment, the oligomer is mixed with the PSA shortly before the PSA is coated.
