Process for producing a semi-aromatic semi-crystalline polyamide |
| abstract |
The present invention relates to a process for the preparation of semi-crystalline semi-aromatic polyamides by direct solid state polymerization of diamine-dicarboxylic acid salts, (a) providing at least two terephthalic acid and diamine salts, each of the diamine / terephthalate being in a solid state and having a melting point Tx of at least 260 캜; (b) preparing a mixture of diamine / terephthalate, wherein the salt is maintained in a solid state; (c) heating the mixture obtained in step (b) in a solid state at a temperature (Tc) of 200 ° C to 260 ° C, applying a pressure less than the saturated water vapor pressure at said temperature to condense and polymerize said salt, Lt; RTI ID = 0.0 > semi-crystalline < / RTI > semi-aromatic polyamide. |
