Molecules carrying associative groups and use thereof as plasticisers

The method of claim 1, wherein the plastic is chosen from cellulose derivatives, polyamides, polymers composed of monomers obtained by reaction of an aliphatic, cycloaliphatic or aromatic C6-C14 dicarboxylic acid with an aliphatic, cycloaliphatic, arylaliphatic or aromatic C6-C2 diamine, acrylic homo- and copolymers, polycarbonate, styrene polymers, halogenated vinyl polymers, polyethers and polymers of vegetable or bacterial origin, polyvinyl acetate, polyvinylbutyral, elastomers, polybutadiene, synthetic polyisoprene, polychloroprene, which are optionally hydrogenated, polyisobutylene, block copolymers of polybutadiene and isoprene with styrene, which are optionally hydrogenated, hydrogenated SBS, poly(styrene-b-butadiene-b-methyl methacrylate), which is optionally hydrogenated, poly(methyl methacrylate-b-butyl acrylate-b-methyl methacrylate), poly(styrene-b-butyl acrylate-b-styrene), random copolymers of butadiene with styrene and acrylonitrile, which are optionally hydrogenated, butyl or halogenated rubbers, polyethylenes, polypropylenes, silicone elastomers of general formula —(Si(R)(CH3)—O)n— with CH3 and R bonded to the silicon atom and the latter bonded to the oxygen atom, wherein R is chosen from methyl, phenyl, vinyl, trifluoropropyl, and 2-cyanoethyl radicals, ethylene/vinyl alcohol copolymers, ethylene/propylene and ethylene/propylene/diene copolymers, copolymers of ethylene with acrylic and vinyl monomers, resins based on methacrylic esters, polyamide/polyether multiblock copolymers, elastomers based on polyesters and polyurethane, recycled rubbers based on thermoplastic elastomers or based on recycled crosslinked rubber, and mixtures thereof.

A plasticizer comprising one of a compound chosen from formula (4) and formula (5):

• [Bm-AB—C]n (4)
• [C—Bm-AB—C]n (5)
• wherein:
• m is an integer chosen from 0, 1, 2 and 3;
• n is an integer chosen from 1, 2, and 3;
• A is chosen from:
• (i) an aliphatic or aromatic ring comprising 5 or 6 carbon atoms, the carbon atoms of said chain and/or of said ring optionally being replaced by one or more atoms chosen from nitrogen, sulfur, and oxygen atoms;
• or
• (ii) a linear or branched and optionally unsaturated carbon-based chain comprising an aliphatic or aromatic ring having 5 or 6 carbon atoms, the carbon atoms of said chain and/or said ring optionally being replaced by one or more atoms chosen from nitrogen, sulfur, and oxygen atoms;
• or
• (iii) a linear or branched carbon-based chain comprising more than 5 carbon atoms, advantageously from 6 to 10 carbon atoms, and optionally an ether or ester functional group;
• B is chosen from amide, ester, imine, ether, sulfonamide, sulfide, phosphate, carbonate, urethane, and biurea functional groups, with the proviso that when more than one unit B is present, the units B can be identical or different;
• and
• C is chosen from imidazolidinyl, bis-ureyl, and ureido-pyrimidyl groups, with the proviso that when more than one unit C is present, the units C can be identical or different.
