Abstract: Disclosed is a method for preparing filled polypropylene compositions comprising mixing a dicarboxylic acid anhydride-grafted polypropylene resin and an ethylene/vinyl acetate copolymer or an ethylene/alkyl (meth)acrylate copolymer with polypropylene, filler and optionally an elastomer. Also disclosed are compositions comprising a dicarboxylic acid anhydride-grafted polypropylene resin and an ethylene/vinyl acetate copolymer or an ethylene/alkyl (meth)acrylate copolymer that can be used as compatibilizers or coupling agents allowing preparation of polypropylene compositions filled with, for example, glass fibers. The glass-filled resin composition exhibits excellent finishing properties, such as adhesion, coating properties, and printability, as well as improved rigidity and thermal properties.

Abstract: A method and apparatus are disclosed for isolating and attenuating shock and vibration in a disk module that includes media drives that are mounted on a printed circuit board (PCB). The apparatus includes a single printed circuit board (PCB), media drives that are coupled to the PCB, a first reinforcing rail that is attached to the PCB and to a first side of a first one of the media drives, a second reinforcing rail that is attached to the PCB and to a first side of a second one of the media drives, and a locking mechanism for locking the first and second rails together.
