摘要: A method is for obtaining a bio-sourced (meth)allylsulfonate alkali salt obtained from a (meth)allyl halide. The (meth)allyl halide is at least partially renewable and non-fossil. A (co)polymer can be obtained from the bio-sourced (meth)allylsulfonate alkali salt. The (co)polymer can be used in a method for enhanced oil and/or gas recovery by sweeping a subterranean formation.

摘要: A bio-sourced cationic polymer is obtained by reaction of epihalohydrin that is least partially renewable and non-fossil, and at least one compound of formula (R1)2N(CH2CH2NH)n(CH2CH2N(R2)2)m that is at least partially renewable and non-fossil. R1 and R2 are, independently of one another, a hydrogen atom H or an alkyl chain including 1 to 8 carbon atoms, n=0 to 3, m=0 or 1. When n=m=0, then a hydrogen atom H is covalently bound to the nitrogen atom N of the N(R1)2 group.

摘要: A method for obtaining diallyldialkylammonium halide includes the reaction between allyl halide and a dialkylamine. At least one of the two is at least partially renewable and non-fossil. The diallyldialkylammonium halide can be used as a bio-sourced diallyldialkylammonium halide monomer to produce a bio-sourced polymer incorporating at least the monomer. The polymer can be used in various technical fields.

摘要: A method for obtaining dimethylaminoethyl (meth)acrylate comprising reacting a (meth)acrylic ester with dimethylaminoethanol that-is at least partially renewable and non-fossil. A bio-sourced dimethylaminoethyl (meth)acrylate has a bio-sourced carbon content ranging between 45 wt % and 100 wt % relative to the total carbon weight in the bio-sourced dimethylaminoethyl (meth)acrylate. The bio-sourced carbon content can be measured according to ASTM D6866-21 Method B.
