  • Publication number: 20200340922
    Abstract: A method for determining the degree of polymerization of a polymer is disclosed, the polymer being contained in a sample (2), the method comprising the following steps: a) illuminating the sample (2) using a laser beam (11) and acquiring (100) a Raman spectrum (S) representative of the polymer; b) identifying (110) a peak of interest (Pi) and determining (120) a position (vi) of the peak of interest in the Raman spectrum; c) on the basis of the position of the peak of interest, using a calibration function (ƒ) to determine a degree of polymerization (DP, DE) of the polymer, the calibration function expressing a variation in the position of the peak of interest as a function of the degree of polymerization of the polymer.

  • Patent number: 10526340
    Abstract: A process for manufacturing crystals of 1,4:3,6-dianhydrohexitols, by manufacturing a solution of an internal dehydration product of at least one hexitol, distilling the solution, crystallizing, and wherein the crystallization mother liquors undergo a step of evaporative crystallization. Unlike the prior art processes that seek to recycle the crystallization mother liquors, evaporative crystallization economically and efficiently replaces the succession of steps consisting of at least one concentration, then at least one step of purification by distillation, chromatography, or crystallization.

  • Patent number: 10174152
    Abstract: A process for producing bis-anhydrohexitol ether compositions and in particular isohexide glycidyl ether compositions, one of the originalities of which is azeotropic distillation carried out under reduced pressure. Such compositions are used to produce epoxy resins, the function thereof being to form a three-dimensional macromolecular network. The compositions obtained according to the process are rich in diepoxy derivatives of isosorbide to the detriment of monoepoxy derivatives, only the first participating in the formation of the three-dimensional network. The crosslinking density is therefore increased, thereby making it possible to obtain a material which is more chemically resistant and mechanically stronger and which has a higher glass transition temperature (Tg), compared with the same materials obtained with bis-anhydrohexitol ether compositions according to the prior art.

  • Publication number: 20170121317
    Abstract: A method for producing a composition of glycidyl ethers synthesised from furan derivatives (furan glycidyl ethers), partly characterized by azeotropic distillation performed under reduced pressure and without the addition of a catalyst. Such products are used to produce epoxy resins, with the aim of forming a three-dimensional macromolecular network. With the compositions of the invention the cross-linking density of the network is increased, allowing the production of a material which is more resistant, both chemically and mechanically, and has a higher glass transition temperature (Tg) than the same materials produced with compositions of furan glycidyl ethers synthesized at atmospheric pressure according to prior art.
