    Abstract: Multi-piece, solid golf balls having a cover material made from a polyurethane/urea hybrid composition are provided. The balls include an inner core preferably made of polybutadiene and may include at least one intermediate layer disposed between the core and outer cover. The cover materials are prepared by first forming a polyurethane prepolymer which undergoes two curing steps. In the first step, the prepolymer is chemically-cured by reacting it with hydroxyl curing agents, amine curing agents, or mixtures thereof. In the second step, the composition is moisture-cured. The cured material may be used to make a golf ball cover having improved durability, cut/tear resistance, and impact strength.

    Abstract: The present invention is a method and apparatus for remote curing of resin-coated surfaces and articles by means of a vaporous curing agent. The method of the present invention includes the steps: (a) providing a surface of the substrate with a layer of a coating precursor comprising a curable material and a stabilized curing agent that is adapted to react with a gaseous, vaporous or aerosol initiating agent to activate the stabilized curing agent so as to cause the curable material to undergo a curing reaction; (b) subjecting the coating precursor to the gaseous, vaporous or aerosol initiating agent for sufficient time to initiate the curing reaction, and allowing the coating precursor to form a cured coating on the substrate. Another variation of the method of the present invention involves the reversal of the positions of the active compounds utilizing the interaction between the gaseous, vaporous or aerosol curing agent and coating precursor comprising a curable material and initiating agent.

    Abstract: Ultra thin organo-ceramic and metal oxide films are prepared under room temperature and atmospheric conditions by exposing .alpha., .omega.--functional siloxane oligomers and fatty acid metal soaps, respectively, to a combination of ultraviolet light (UV) and ozone (O.sub.3). The process includes the steps of preparing ultra thin .alpha., .omega.--functional polysiloxane and fatty acid metal soap films using, but not limited to, the Langmuir-Blodgett (LB) technique. The LB technique permits construction of molecular monolayer or multilayer films on a variety of substrates. By using carboxylic acid end groups on the siloxane oligomers, metal ions can be incorporated into the SiO.sub.x film after UV-ozone exposure. This technique can be used to make electronically, optically, and chemically important organo-ceramic and metal oxide films on temperature sensitive substrates.
