摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

摘要:The present invention relates to a solid phase peptide synthesis (SPPS) where the coupling of amino acids is performed in an aqueous solution comprising at least one organic co-solvent miscible with water. The aqueous solution is capable of sufficiently solubilize the activated Fmoc-α-amine protected amino acid or activated Fmoc-α-amine protected peptide fragment, and where the resin is capable of swelling in the presence of the aqueous solution above about 4 mLg-1. The invention also encompasses a method for regeneration of spent aqueous solution from the SPPS.
