Title (EN) POLYAMIDE PA 6-6 SYNTHESIS PROCESS
(FR) PROCÉDÉ DE SYNTHÈSE DE POLYAMIDE PA 6-6
Abstract:
(EN) The present invention relates to a polyamide PA 6-6 synthesis process comprising: -a first step of reacting, in the presence water, a compound of formula (I) R0COO–(CH2)4–COOR'0 (I), in which R0 and R'0, which may be identical or different, represent H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, with hexamethylenediamine (HMDA) at a temperature less than or equal to 60°C, so as to form a reaction medium, then -a second step of heating the reaction medium to a temperature greater than or equal to 200°C; wherein the reaction medium also comprises: -a compound of formula (A): R1-COO-(CH2)n-CH=CH-(CH2)n-COO-R2 (A) -and/or a compound of formula (B): R3-(CH2)m-CH=CH-(CH2)n-COO-R4 (B) in which: R1 , R2 and R4, which may be identical or different, represent H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, R3 represents -CN or -COOR5, R5 representing H or a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, m represents 0, 1 or 2 and n is an integer between 7 and 13, limits inclusive.
(FR) La présente invention concerne un procédé de synthèse de polyamide PA 6-6 comprenant: -une première étape de réaction, en présence d'eau, d'un composé de formule (I) R0COO–(CH2)4–COOR'0 (I), dans laquelle R0 et R'0, identiques ou différents, représentent H ou un radical alkyle linéaire ou ramifié comprenant de1 à 4 atomes de carbone, avec de l'hexaméthylène-diamine (HMDA) à une température inférieureou égale à 60 °C, pour former un milieu réactionnel, puis -une deuxième étape de chauffage du milieu réactionnel à une température supérieure ou égale à 200 °C; le milieu réactionnel comprenant en outre: -un composé de formule (A): R1-COO-(CH2)n-CH=CH-(CH2)n-COO-R2 (A) -et/ou un composé de formule (B): R3-(CH2)m-CH=CH-(CH2)n-COO-R4 (B) dans lesquelles:R1,R2, et R4, identiques ou différents, représentent H ou un radical alkyle linéaire ou ramifié comprenantde 1 à 4 atomes de carbone,R3 représente -CN ou -COOR5,R5 représentant H ou un radical alkyle linéaire ou ramifié comprenantde 1 à 4 atomes de carbone, m représente 0, 1 ou 2 et n est un entier compris entre 7 et 13, bornes incluses.
