A continuous process for making a pressure-sensitive adhesive is disclosed. A mixture comprising natural rubber having a Mooney viscosity of 85 to 100, a tackifier, a filler, and 0.1 to 5 wt. % of an added C.sub.12-C.sub.24 fatty acid based on the amount of mixture is masticated in a first section of a single- or twin-screw extruder. Mastication of the mixture continues in at least one subsequent extruder section in the presence of additional tackifier. The product is a homogeneous, reduced-viscosity pressure-sensitive adhesive. The minor proportion of added C.sub.12-C.sub.24 fatty acid aids mastication of the rubber and enables high throughput without addition of peptizers. Duct tapes made from the adhesives display improved adhesion to steel, better adhesion bond strength, and enhanced seven-day clean removability from even difficult substrates such as marble or ceramic tile.

A polyamide resin composition for an extrusion-molded article exposed to high-pressure hydrogen gas contains: 70 to 99 parts by weight of a polyamide 6 resin (A); 1 to 30 parts by weight of an impact modifier (B); and 0.005 to 1 parts by weight of a metal halide (C) with respect to a total of 100 parts by weight of the polyamide 6 resin (A) and the impact modifier (B). The polyamide resin composition has a melt tension of 20 mN or more when measured at 260° C. and a take-up speed at strand break of 30 m/min or more when measured at 260° C.

The present invention relates to a metal matrix composite (MMC). The MMC includes a preform formed from a composition having ceramic particles and ceramic fibers and defining a plurality of voids. The metal matrix composite also includes a support element, such as a metal, disposed within the voids of the preform. The MMC has a wear surface defined by both the preform and the support element.

A coupling agent formulation for cellulosic material-polymer composites is provided. The formulation includes a) at least one organic peroxide; and b) at least one of i) at least one zinc-containing reagent; and/or ii) at least one silicon-containing reagent. The coupling agent formulations produce polymer matrix cellulosic material composites with improved strength and aging characteristics. The improved strength may be related to physical properties such as improved stiffness, toughness or tensile strength. A masterbatch utilizing the coupling agent formulation is provided, as well as a method making the masterbatch.
