Abstract: The present invention provides an allophanate polymer system made by a method comprising combining a neutralized polyol with a polyuretdione resin in the presence of a reactive reducer comprising a reducing agent and a tertiary amine catalyst to produce a clear-coat, and contacting the clear-coat with a basecoat comprising a tertiary amine catalyst. The reaction between the polyol and the polyuretdione will proceed after the reactive reducer reduces the viscosity of the one component clear-coat formulation to appropriate levels. The inventive allophanate polymer system is particularly applicable in providing coatings, adhesives, castings, composites, and sealants with good performance.

Abstract: A hybrid absorbent foam includes an integrated hybrid foam layer having an open surface, a closed surface, and a foam body extending between the open and closed surfaces. The integrated hybrid foam layer has an open-cell content of at least 50%, while the closed surface provides a barrier to aqueous liquids. The integrated hybrid foam layer is formed as a single layer, and has a substantially uniform polymer composition throughout its thickness. The integrated hybrid foam layer combines the functions of liquid absorbency, retention, and barrier into a single layer, and is useful in a wide variety of absorbent articles.

Abstract: A system (20) and method are disclosed for the self-calibrating, on-line determination of size distribution f(x) and volume fraction ? of a number of particles (P) dispersed in a medium (M) by detecting one or more propagation characteristics of multiply scattered light from the particles (P). The multiply scattered light is re-emitted in response to exposure to a light source (21) configured to provide light at selected wavelengths. The determination includes calculating the isotropic scattering and absorption coefficients for the particles (P) by comparing the incident and detected light to determine a measurement corresponding to the propagation time through the scattering medium (M), and iteratively estimating the size distribution f(x) and volume fraction ? as a function of the coefficients for each of the wavelengths. An estimation approach based on an expected form of the distribution and the mass of the particles is also disclosed.
