    Abstract: Conventional curable polymers tend to shrink upon curing whilst low shrinkage ultraviolet light curing polymers have a problem with respect to curing below surface areas of a component. By providing light transmitting elements and/or local ultraviolet light source precursors, greater depth of ultraviolet curing can be achieved and therefore enhanced acceptability with regard to component manufacture. The light transmitting elements may be formed by optic fibers or coatings to existing reinforcing fibers or through consideration of the refractive index of the cured and uncured polymer to create light transmission paths through the component. Ultraviolet light source precursors can be activated by heat or a “seed” light exposure or vibration to create localised ultraviolet curing of the polymer thereabout.

  • Publication number: 20140039084
    Abstract: The present invention aims to provide a surface modification method for a rubber vulcanizate or a thermoplastic elastomer, which can impart excellent sliding properties and excellent durability against repeated sliding motion and can allow the surface to maintain the sealing properties, without using expensive self-lubricating plastics. 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.
