A solid organic material comprising at least one amphiphilic block copolymer of the methacrylic type, the block copolymer being dispersed in a polymer matrix, the block copolymer having a number-average molar mass (Mn) greater than or equal to 20 000 g/mol; a method for preparing said solid organic material; use of said solid organic material for antibacterial, antimicrobial, antiviral, anti-inflammatory and/or antifungal applications; a medical device comprising said solid organic material.

Solid organic antibacterial material

A method for manufacturing microcapsules containing an active substance, the method including: providing an aqueous solution of a surfactant, an oily phase comprising the active substance and a first monomer, and a polar phase comprising a second monomer; preparing an oil-in-water emulsion by adding the oily phase to the aqueous solution of the surfactant; adding the polar phase to the oil-in-water emulsion, in order to obtain a polymer in a reaction mixture, by polymerization of the first monomer and the second monomer; isolating the microcapsules, including a wall formed by the polymer and containing the active substance, from the reaction mixture; wherein the polymer is a poly(beta-amino ester). Microcapsules obtained by the method.

Method for preparing biodegradable microcapsules and microcapsules thus obtained

The invention pertains to an improved PVDC composition including certain dienophiles qualified for food contact, which possess an optimized balance of effectiveness in preventing discoloration upon exposure to radiation, with no negative impact on the barrier properties, in particular sorbate esters of formula (I), wherein Ris a C-Chydrocarbon group, preferably a C-Calkyl group, to layers made therefrom, to multi-layer assemblies comprising the same, and to the use of said assemblies for packaging, in particular for packaging foodstuffs.
