摘要： The present invention relates to a method for preparing a dispersion of polyurethane particles, which comprises the following steps: a) placing at least one (poly)isocyanate monomer and at least one polyol monomer of formula (I): (I) in the presence of an aqueous phase comprising at least one surfactant and an organic phase comprising at least one polymerisation catalyst, thus obtaining a two-phase mixture; b) emulsifying the two-phase mixture obtained in step a), thus obtaining a miniemulsion of oil-in-water, formed by droplets of said organic phase, with a mean size of 50 nm to 500 nm, dispersed in said aqueous phase; and c) polymerising the (poly)isocyanate and polyol monomers of formula (I), thus obtaining solid particles of polyurethane, with a mean size of 50 nm to 500 nm, dispersed in said aqueous phase. Figure: none.

摘要： The invention relates to a method for the metathesis of olefin(s). The method according to the invention comprises bringing at least one fatty acid ester or a fatty acid into contact with a metathesis catalyst, said fatty acid ester or fatty acid comprising at least one unsaturation, wherein the ester or the fatty acid is treated with a sorbent before being brought into contact with the metathesis catalyst, the sorbent being maintained in the reactive medium while the ester or the fatty acid is brought into contact with the metathesis catalyst.
