  • Polyether based monomers and highly cross-linked amphiphile resins
    Patent number: 7842767
    Abstract: The present invention relates to a cross-linked polyether which is obtained by polymerization of at least one monomer selected from the group consisting of (a) (?-X-methyl) vinyl-EWG, (?-X-methyl) vinyl-ERG, or (?-X-methyl) vinyl-aryl, where X is oxygen, sulfur, PEG, PPG or poly (THF); (b) a monomer which is polymerizable with a PEG, PPG or poly (THF) cross-linker having at least one (?-X-methyl) vinyl-EWG, (?-X-methyl) vinyl-ERG or (?-X-methyl) vinyl-aryl, where X is oxygen, sulfur, PEG, PPG, or poly (THF); (c) a PEG, PPG, or poly (THF) cross-linker having at least an acrylamide or a methacrylamide end group; and (d) mixtures thereof. Various monomers, resins and methods for preparing such cross-linked polyethers are also disclosed.

  • Amphiphile solid support for peptide synthesis, bioorganic and organic chemistry
    Patent number: 7235297
    Abstract: The present invention fulfils desired specifications generally rarely encountered with existing solid supports such as highly amphiphile behaviour. The solid support described herein is a poly(ethylene or propylene)glycol based polymer that can be useful in solid and liquid phase synthesis, chromatography, scavenging purposes and immobilisation of proteins and reagents. More specifically, the solid support is a cross-linked polyether derived from a cross-linked polyester which is obtained by copolymerization of at least one monomer comprising (a) one-ended polymerizable vinyl or allyl ketone, ester, ether or mixtures thereof with at least one cross-linker having at least two polymerizable terminal end groups, with the exception of epoxy and oxetane end groups, or (b) divinyl benzene. The method for the preparation of the cross-linked polyether is also disclosed.

  • Process for the regeneration of used silica gel
    Patent number: 6248683
    Abstract: The present invention is concerned a process for the regeneration of the spent silica gel used in chromatography and for any other kind of silica. The process comprises 5 main steps, namely: washing with an extractant of organic compounds and removing volatile organic materials remaining thereafter; oxidation to oxidize organic compounds remaining and, preferably, bleach the material; washing with an acid to remove soluble inorganic matter; heating to dry the material and combust any remaining organic compounds present; and recovering the regenerated material. Various optional steps can be added to the process.
