摘要： The invention relates to a core-shell-type multilayer particle comprising at least one layer B that comprises at least one photoactive monomer bearing a photoisomerizable chromophore and a rigid shell A. The photoactive monomer has the following formula (I): (I) in which: X denotes H or CH3-; G denotes =O-C(=O)-, -C(=O)-O-, a substituted or unsubstituted phenyl group, or else -NR-C(=O)-, NR being bonded to L and R being H or a C1-C10 alkyl group; L denotes a spacer group; CR denotes a photoisomerizable chromophore. It is possible to use the multilayer particle of the invention to achieve optical storage of 2D data.

摘要： The invention relates to materials having rubber-like elasticity and comprising molecules with a mass of between 9 and 9000 g/mole, all or part of said molecules having at least three groups (also known as associative groups) that can associate by means of noncovalent interactions. The inventive material, which comprises non-polymerised and non-chemically-crosslinked small molecules, has rubber-like elasticity properties. In one embodiment of the invention, the material has rubber-like elasticity at ambient temperature. Above a certain temperature, the material flows like a simple liquid. The material is thermoreversible, i.e. a material with rubber-like elasticity can be obtained once again by means of cooling. In addition, the invention comprises a self-healing material that is potentially recyclable, which is never the case with a chemically-crosslinked elastomer. According to one embodiment of the invention, the molecules forming the inventive material bear associative groups having formula (1), in which A denotes oxygen, sulphur or NH, whereby the carbon atoms on formula (1) can be substituted. A preferably denotes oxygen. Advantageously, the material comprises (i) molecules having at least 3 associative groups and (ii) molecules having a single associative group. Moreover, the molecules are preferably obtained from fatty acid derivatives.

摘要： The invention relates to the production and use of block copolymers which are obtained by means of controlled radical polymerisation in the presence of nitroxides for the purpose of reinforcing fragile polymer matrices. The invention offers advantages such as (i) simplicity of copolymer synthesis and use and (ii) fine dispersion of the copolymer molecules in the fragile matrix, which ensures both the transparency of the material and high reinforcement against impact. More specifically, the invention relates to the radical synthesis of block copolymers comprising at least three blocks, which include one block having a glass transition temperature of less than 0 °C and a thermoplastic end block having a glass transition temperature of more than 0 °C, thereby guaranteeing compatibility with the fragile matrix to be reinforced against impact.

摘要： The invention relates to a method for increasing the compatibility between at least two polymers, which comprises: (a) selecting at least two immiscible polymers (A) and (B), at least one of which does not bear a nitrogenous heterocycle-based associative group, and (b) modifying the polymer (A) and/or the polymer (B) so as to obtain a blend of polymers (Pi) which are derived from the polymers (A) and (B) and which each bear nitrogenous heterocycle-based associative groups, said associative groups being present in sufficient amount for the polymers (Pi) to be more compatible with one another than the polymers (A) and (B). It also relates to the polymer composition that can be obtained according to this method.

摘要： The present invention relates to a composition containing at least one (meth)acrylic polymer and at least one copolymer containing motifs from at least one first monomer (A), enabling compatibility with said (meth)acrylic polymer, and at least one second motif (B) carrying an associative group. The invention also relates to the use of such a copolymer having associative groups to improve the properties of a (meth)acrylic polymer. The invention also relates to uses of the abovementioned composition.
