AMORPHOUS HIGH PERFORMANCE POLYAMIDE |
| 摘要 |
The disclosure relates to an improved method of producing MPMD based amorphous, semi-aromatic polyamides in order to improve their mechanical properties. It also relates to improved formulations of these polyamides which have further improved mechanical properties by the incorporation of greater amounts of isophthalic acid.

1. A composition comprising a copolyamide containing about 40 to about 80 mol % 2-methyl-1,5-pentamethyleneterephthalamide (“MPMD-T”) units and about 20 to about 60 mol % 2-methyl-1,5-pentamethyleneisophthalamide (“MPMD-I”) units, wherein the copolyamide has a relative viscosity (“RV”) of more than 1.90. |
