Abstract: Described are compositions comprising a fluorine containing or fluorine and silicon containing polymer, with a reactive diluent, and optionally non-reactive oligomeric additives, crosslinkers, or inorganic particles, which upon curing provides coatings with a good balance of adhesion, mechanical properties, scratch resistance, low surface energy, repellency, and transparency. The compositions are useful as a topcoat, particularly in optical applications.

Abstract: A composite sheet comprises a substrate and a multi-layer coating on its outer surface, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes a olefin group and a moisture curable group, such as an isocyanate or silane group. The function of the polymeric layer includes protecting the metal layer from corrosion. A production process for the composite sheet includes depositing the precursor and exposing it to both beam radiation and moisture, which respectively promote polymerization and curing at different sites of the precursor. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation.

Abstract: A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a composition capable of being polymerized and/or cross-linked by free-radical processes. After the precursor is applied, the composite sheet is exposed to beam radiation and ozone, which both promote conversion of the precursor. The function of the cured polymeric layer includes protecting the metal layer from corrosion. The use of both beam radiation and ozone promotes substantially full conversion and curing of the precursor, even in portions of the substrate that are geometrically shadowed from incident beam radiation.

Abstract: Blends comprising 65-95 wt % poly(trimethylene terephthalate-co-sebacate), 5 to 35 wt % polylactic acid and a chain extender are provided that exhibit greatly increased melt strength compared to that of poly(trimethylene terephthalate-co-sebacate) alone. Such improvements allow these compositions to be processed readily by melt-blowing, which is useful for packaging and for preparing items such as biodegradable garbage bags.
