    Abstract: Biocompatible polymers are manufactured to include an amino acid mimetic monomer and one or more hydrophobic acrylate monomers. The amino acid mimetic monomers are selected to mimic the side chain of the amino acids asparagine or glutamine. The amino acid mimetic monomer can be a methacryloyl or acryloyl derivative of 2-hydroxyacetamide, 3-hydroxypropionamide, alaninamide, lactamide, or glycinamide. These amide functional groups offer the advantage of moderate hydrophilicity with little chemical reactivity. The amino acid mimetic monomer can be copolymerized with one or more hydrophobic acrylate monomers to obtain desired coating properties.

The adhesive complex coacervates are composed of a mixture of one or more polycations, one or more poly anions, and one of more multivalent cations. The polycations and polyanions in the adhesive complex coacervate are crosslinked with one another by covalent bonds upon curing. The adhesive complex coacervates have several desirable features when compared to conventional bioadhesives, which are effective in water-based applications. The adhesive complex coacervates described herein exhibit good interfacial tension in water when applied to a substrate (i.e., they spread over the interface rather than being beaded up). Additionally, the ability of the complex coacervate to crosslink intermolecularly increases the cohesive strength of the adhesive complex coacervate. The adhesive complex coacervates have numerous biological applications as bioadhesives and drug delivery devices.

  • Patent number: 7838037
    Abstract: The present invention provides methods for microencapsulation of active ingredients for topical application, whereby double-layer and triple-layer microcapsules are obtained. The microcapsules protect the active ingredients, maintain their original activity throughout processing, formulation and storage, and enable controlled release of the active ingredient only upon application onto the skin.

  • Publication number: 20100273910
    Abstract: The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matt effect.

  • Publication number: 20100261136
    Abstract: The invention relates to a dental composition comprising a hardenable powder to be used in a process for retraction of dental tissue. The invention also relates to a kit of parts comprising the dental composition comprising a hardenable powder, a hardening agent, optionally a handpiece of a powder jet device, optionally a powder jet device, and optionally retraction caps. In a further aspect, the invention relates to a method for retracting dental tissue comprising the steps of applying a dental composition comprising a hardenable powder with a powder jet device into the sulcus between soft and hard dental tissue, applying a composition comprising a hardening agent either before or after the previous step, leaving the dental composition in the sulcus for a time sufficient to effect retraction of the soft dental tissue and removing the dental composition from the sulcus.
