| titleOfInvention | Polyamide pa 6-6 synthesis process |
| abstract | 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. |
