ABSTRACT:
This invention is a hot melt pressure sensitive adhesive formed by copolymerizing acrylic, or a combination of acrylic and vinyl, monomers, at least one of which is a photoinitiator, with the functional monomer, 1-(1-isocyanato-1-methyl ethyl)-3-(1-methyl ethenyl)benzene (m-TMI), to give a saturated polymer with pendant vinyl groups that are crosslinked by UV radiation.
