The present invention relates to the preparation of longchain aliphatic polyamides, and a method of producing the same. The production method utilizes a nylon salt preparation method of controlling the stoichiometric ratio between the diamine and dicarboxylic acid, resulting in polyamides with high purity, high number average molecular weight (≥37,000 g⋅mol-1) and narrow polydispersity. Furthermore, these novel polyamides display superior water barrier/adsorption, higher number average molecular weights, better retention of physical properties at elevated temperature (≥Tg) and easier processability and polyolefin-compat- ibility than conventional polyamides. The polyamides are suitable for use in packaging films, furniture, appliances, consumer goods, wire and cable, and automotive components.
