    Abstract: Compositions and processes for development of sustainable materials based upon a method of thermoplastic polymer recycling with a solvent that is also a monomer for renewable polymer synthesis. By combining petroleum-derived polymers with bio-based monomer feedstocks, biphasic, blended polymer products are produced and are shown to exhibit facile tunability of physical and material properties. This one-pot, solvent-based recycling approach yields neat recycled products without the use of solvent evaporation or solute precipitation, and the functional utility of the resulting polymer blends greatly exceeds that of either homopolymer alone.

  • Patent number: 7838571
    Abstract: Photopolymerizable polymer composites based on dimethacrylate systems have been increasingly utilized as dental restorative materials. One of the biggest drawbacks of current dental resin systems is the volume shrinkage and shrinkage induced stresses that arise during the polymerization. Other major problems include incomplete double bond conversion and insufficient wear resistance. This invention involves the development of an entirely novel approach to the photopolymerization process that utilizes thiol-ene systems as low shrinkage and ultra-low shrinkage stress dental restorative materials. Compared with the traditional dimethacrylate dental resins, these novel photopolymerizations have demonstrated a dramatically decreased volume shrinkage, extremely rapid polymerization, abilities to photopolymerize ultrathick materials and achieve much higher conversion, lack of oxygen inhibition and ultra-low shrinkage stress due to low volume shrinkage and drastically delayed gel point conversion.

  • Patent number: 7767727
    Abstract: An autoxidisable architectural coating composition suitable for application to surfaces found in and around buildings at ambient temperatures and in natural daylight wherein surface autoxidation of the composition is promoted by a combination of low concentrations of metal ions (especially manganese or vanadium) and 2,2-dimethoxy-1,2-diphenylethan-1-one as photoinitiator. The composition avoids the need to use more than trace amounts cobalt ions which are rumoured to be carcinogenic yet achieves adequately fast rates of autoxidation. Preferably the use of cobalt is avoided altogether. The use of the low concentrations of the other metal ions reduces discoloration of the compositions often to levels below what is achieved using conventional cobalt promoters. Also a modification in which surface autoxidation is promoted by a combination of 2,2-dimethoxy-1,2-diphenylethan-1-one and trace amounts of cobalt ions in the absence of other surface autoxidation promoting metal ions.

  • Publication number: 20090270528
    Abstract: The disclosure provides a new photopolymerizable resin system for dental restorative materials. The resin system utilizes a thiol-ene component as the reactive diluent in dimethacrylate systems. The ternary resin system comprises a thiol monomer, an ene monomer and a dimethacrylate monomer. Use of an off-stoichiometric ratio of thiol:ene functional groups in favor of excess thiols results in enhanced overall functional group conversion, improved polymer mechanical properties, and reduced shrinkage stress of the ternary system when compared to either traditional dimethacrylate or thiol-ene resin systems.
