    摘要： The invention provides poiyfunctionai bio-based methacrylate oligomers, which are synthesized via the ring-opening reaction between at least one ethyienicaliy unsaturated acid selected from methacrylic acid, acrylic acid, and crotonic acid, and a poiyfunctionai bio-based epoxy resin, such as epoxidized sucrose soyate. The extent of reaction may be varied to generate a family of methacrylate oligomers with differing degrees of methacryiation. These methacrylate oligomers can optionally be mixed with a reactive diluent, such as styrene, and cured using, for example, a thermally-activated free radical initiator to form a thermoset polymer with high modulus. The thermosets can be used to form composites, adhesives, coatings, and dental restorative materials. Methods of making the methacrylate oligomers are disclosed as are coating compositions and coated objects, such as dental restorative materials, using the methacrylate oligomers.

    摘要： Oxygen barrier compositions for electrical devices and their related methods are provided. In certain embodiments, the oxygen barrier compositions comprise a meta-substituted aromatic resin and an additional aromatic epoxy resin. In some embodiments, the compositions have a chlorine content of less than approximately 1000 ppm. The compositions may have an oxygen permeability of less than approximately 0.4 cm3·mm/m2·atm·day at approximately 0% relative humidity and approximately 23° C. In certain embodiments, methods of curing the oxygen barrier compositions comprise partially curing the composition where, the partial cure is achieved through ultraviolet radiation or heat.
