<P>PROBLEM TO BE SOLVED: To provide a butyl adhesive containing maleic anhydride and optional nanoclay. <P>SOLUTION: Disclosed are an adhesive polymer containing maleic anhydride-grafted butyl rubber, and a polymer compound produced from the adhesive polymer and furthermore containing functionalized silica nanoclay. The adhesive polymer and the polymer compound exhibit highly improved adhesiveness to the surface of a specific substrate. The substrate material includes stainless steel, glass, Mylar (R) and Teflon (R). The maximum adhesive force was observed in a polymer compound comprising maleic anhydride-grafted butyl rubber produced by a solution method and 5 to 15 phr of montmorillonite nanoclay. The adhesive force is improved by increasing the level of nanoclay content in the compound to a limit causing a filler-filler interaction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
