The present invention relates to a surface modification method for modifying a rubber vulcanizate or a thermoplastic elastomer as an object to be modified, the method including: step 1 of forming polymerization initiation points on the object to be modified; step 2 of radically polymerizing a monomer, starting from the polymerization initiation points, by irradiation with LED light at 300 nm to 400 nm to grow polymer chains on a surface of the object to be modified; and step 3 of esterifying, transesterifying or amidating side chains of the polymer chains.

  • Patent number: 8940806
    Abstract: The invention relates to the use of triazenes of formula (I) wherein Q is a direct bond or a bivalent radical —(CR8R9)—, Z1 is —O—, —NR10—, —CH2—, —(CR11R12)— or —C(?O)— and R1 to R12 are optionally substituted hydrocarbon residues, as precursors for radicals useful in reactions triggered by free radicals, such as polymerization of unsaturated monomers and degradation of polyolefins. Most of the triazenes of formula (I) are novel and claimed, too, as well as the preparation of triazenes of formula (I) and polymerizable compositions comprising them.

  • Patent number: 8933143
    Abstract: Compositions and methods for adjustable lenses are provided. In some embodiments, the lenses contain a lens matrix material, a masking compound, and a prepolymer. The lens matrix material provides structure to the lens. The masking compound is capable of blocking polymerization or crosslinking of the prepolymer, until photoisomerization of the compound is triggered, and the compound is converted from a first isomer to a second isomer having a different absorption profile. The prepolymer is a composition that can undergo a polymerization or crosslinking reaction upon photoinitiation to alter one or more of the properties of the lenses.
