This adhesively joined structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion includes an organic resin phase containing one or more of a urethane group, an epoxy group, and an ester group; an organic compound phase formed of an organic silicon compound; and optionally an inorganic compound phase formed of an inorganic silicon compound. The total volume percentage of the organic compound phase and the inorganic compound phase to the total volume of the film portion is 16 vol % to 84 vol %. The volume percentage of the organic compound phase to the total volume of the film portion is 16 vol % to 84 vol %. The volume percentage of the inorganic compound phase to the total volume of the film portion is limited to 10 vol % or less. The organic silicon compound includes a SiC bond; and a SiO bond or a SiOH bond or a combination thereof.

An enhanced performance roofing membrane, having: (a) a bottom membrane layer; (b) a top membrane layer; (c) a scrim layer between the top and bottom membrane layers; and (d) a reduced density membrane layer between the top and bottom membrane layers. The reduced density membrane layer may be a foamed layer, or a layer of polymer with gas pockets or beads therein. The reduced density layer may be made of the same materials as the top and bottom layers.

The disclosure provides a cross-linkable polymer composition, a core layer for an information carrying card comprising such cross-linked composition, resulting information carrying card, and methods of making the same. An information carrying card includes a body defining a first cavity and a second cavity. The first cavity has a first area and the second cavity has a second area. The first cavity is continuous with the second cavity and the second area is less than the first area. A circuit element is disposed within the first cavity.

A multilayer structure having a polyolefin layer and a water-absorbing layer is provided. The multilayer structure may be in the form of a tubular structure and is particularly useful in optical fiber applications. A system and method for preparing micronized polymer pellets is also provided. The micronized polymer pellets include a polymer resin and particles comprising a superabsorbent polymer.
