Abstract
There are synthesized certain polycylic-vinyl reactive tackifiers for acrylic based pressure-sensitive adhesive polymers. The compounds have reactive pendant vinyl groups which copolymerize and graft to the adhesive polymer by means of UV or EB radiation. There are also provided novel pressure-sensitive adhesive compositions containing such reactive tackifiers.
