  • Publication number: 20210024534
    Abstract: A process for manufacturing chromenes intended for the preparation of thermosetting resins, includes transforming an aromatic propargyl ether of general formula (I) into a chromene by homogeneous gold(I) catalysis with the catalyst (acetonitrile)[(2-biphenyl)di-tert-butylphosphine]gold(I) hexafluoroantimonate in an organic solvent under an inert or non-inert atmosphere. Moreover, a process for preparing a material made of thermoset resin, includes successively a) implementation of the above process; polymerization of the reaction product obtained in step a) so as to obtain the material made of thermoset resin; c) recovery of the material made of thermoset resin obtained in step b).

  • Publication number: 20210024533
    Abstract: A process for manufacturing chromenes which are intended for the preparation of thermosetting resins, includes transforming an aromatic propargyl ether of general formula (I) into a chromene by flash vacuum thermolysis, at a temperature of between 300 and 600° C., at a pressure of between 4 and 10 000 Pa. It also concerns a process for preparing a material made of thermoset resin, including successively: a) implementation of the above process; b) polymerization of the reaction product obtained in a) so as to obtain the material made of thermoset resin; c) recovery of the material made of thermoset resin obtained in b).

  • Publication number: 20210024535
    Abstract: A process for producing chromenes intended for the preparation of thermosetting resins, includes converting an aromatic propargyl ether of general formula (I) into a chromene by homogeneous catalysis with copper salts in anisole at a temperature between 100 and 170° C. Moreover, a process for preparing a material made of thermoset resin, includes successively a) carrying out the above process; b) polymerizing the reaction product obtained in a) so as to obtain the material made of thermoset resin; c) recovering the material made of thermoset resin obtained in b).

  • Patent number: 10829581
    Abstract: The invention relates to a curable resin that represents an excellent substitute for phenolic resins and is therefore able to replace phenolic resins in all applications in which they are used. Said resin is characterised in that it comprises: (1) at least one prepolymer resulting from the prepolymerisation of a compound A comprising at least one aromatic or heteroaromatic ring, a first group —O—CH2-C?CH and at least one second group selected from the groups —O—CH2-C?CH2 and —CH2-CH?CH2, said groups being carried by the at least one aromatic or heteroaromatic ring; and (2) a compound B comprising at least two thiol groups (—SH). The invention also relates to a material obtained by curing said curable resin, and in particular to an ablative composite material. The invention further relates to a material obtained by curing said curable resin.
