  • Patent number: 8193296
    Abstract: This disclosure relates to golf balls made from a crosslinked thermoplastic polyurethane elastomer. The crosslinked thermoplastic polyurethane elastomer includes crosslinks located in the hard segments, where the crosslinks being the reaction product of unsaturated bonds located in the hard segments as catalyzed by a free radical initiator. The crosslinks may be formed from an unsaturated diol as a chain extender. The unsaturated diol may be trimethylolpropane monoallylether (TMPME). The golf ball may include the crosslinked thermoplastic polyurethane elastomer in the cover layer, in which case the cover layer may exhibit a high degree of scuff resistance.

  • Publication number: 20110244695
    Abstract: The present invention relates to a method for preparation of an ultraviolet (UV)-curable inorganic-organic hybrid resin containing about or less than 4% volatiles and less than 30% organic residues. The UV-curable inorganic-organic hybrid resin obtained according to this method can be UV-cured within a markedly very short time and enables, upon curing, the formation of a transparent shrink- and crack-free glass-like product having high optical quality, high thermal stability and good bonding properties. In view of these properties, this hybrid resin can be used in various applications such as electro-optic, microelectronic, stereolithography and biophotonic applications.
