Abstract: A padded construction useful for straps or irregularly-shaped articles is provided which includes a pair of opposed outer panels and a core sandwiched between the outer panels with side margins extending between the latter and having the core between the side margins. One of the outer panels and the side margins are formed of a closed cell neoprene synthetic resin foam material, whereas the core includes a length of synthetic resin (e.g., nylon or polyester) webbing. In one embodiment, the outer panels and side margins are integrated to present a tubular section of the neoprene foam material, and the core is disposed within the tubular section; an exterior decorative leather piece may be attached by sewing through the tubular subassembly. In another embodiment, the core includes an internal leather strap to which the webbing is attached, and neoprene is first applied to the core subassembly and is wrapped around the side margins thereof in an overlapping fashion.

Abstract: The cured reaction product of a polyalkylenepolyamine and a polyepoxide is useful as a weak base ion exchange resin. For example, the reaction of triethylenetetramine and diglycidyl ether of bisphenol A forms a weak base resin having an excellent total weak base capacity.
