Copolyamides based on hexamethylene diamine of adipic acid and dimer acids, and processes for their preparation |
| abstract |
The copolyamides have a composition such that the molar ratio of adipic acid relative to the total acids is between 0.5 and 0.99 and a melting point such as the point obtained by abscissa the molar fraction of adipic acid and on the ordinate, the melting temperature of the copolyamide, determined by differential microcalorimetry with a temperature variation of 10 ° C. per minute, is included in the area ABCD plotted on the graph represented in the appendix.n n n Various specific processes are described: either in a heterogeneous medium, a phase of homogenization of the prepolymer then being necessary, are in a homogeneous medium in the presence of a solvent having a melting point of between 170 and 250 ° C.n n n The copolyamides having the claimed composition and obtained by the claimed processes are flexible and homogeneous. |
