Abstract: Amino alkoxy-modified silsesquioxanes (amino AMS), and/or amino co-AMS compounds that also comprise a mercaptosilane or a blocked mercaptosilane, are excellent adhesives for coating plated or unplated metal wire for adherence of the wire to a rubber stock. The amino AMS and/or the amino/mercaptan co-AMS adhesives can be used with all types of rubber and there is no requirement for the use of special adhesive additives to the rubber vulcanizates, such as, but not limited to, cobalt, resins and high sulfur levels. In particular, the use of amino AMS and/or amino/mercaptan co-AMS compounds as adhesives for bonding wire to rubber also improves the adherence performance of the reinforcements to obtain sufficient bonding that is resistant to degradation over the course of time, especially resistance to thermal aging and/or thermo-oxidizing aging, in particular corrosion in the presence of water.

Abstract: The method of making polyolefin with a silicon nitride nano-filler uses silicon nitride (SiN) as a promoter for in situ polymerization with a zirconocene catalyst. The method includes adding the bis(cyclopentadienyl) zirconium dichloride catalyst and nanoparticles of silicon nitride to a reactor. The reactor is then charged with toluene and a methylaluminoxane co-catalyst, and is heated for a period of time sufficient to bring the reactor to a polymerization reaction temperature. Nitrogen gas is removed from the reactor following the heating, and then ethylene monomer is fed into the reactor, initiating polymerization. The polymerization is then quenched, and non-reacted monomer is vented. The polyolefin product is then removed from the reactor, washed and dried.
