  • Radiation sterilizable pressure sensitive adhesives
    Patent number: 6037430
    Abstract: A method of improving the strength properties of acrylic-based pressure sensitive resins exposed to sterilizing radiation by using, during interpolymerization of the monomers of the resin, an amount of chain transfer agent adequate to reduce the gel content of the resin to an extent effective to counteract the gain in gel content occurring after exposure to such radiation. The gel content of the resin composition, as made, is no more than about 2.0%.
