Latest Patents

Katsumi Akaike holds a patent for a polyamide production method. This method involves polycondensating a polyamide precursor containing a salt made from a dicarboxylic acid and a diamine under pressure in a pre-polymerization tank to obtain a prepolymer. The process continues with the highly polymerization of the prepolymer using an extruder. A critical aspect of this method is the relationship between the length of the discharge side pipe and the linear velocity of discharge, which must satisfy the equation, 0.1 [s] ≤ L/v < 10 [s]. This innovative approach aims to optimize the production process and improve the properties of the resulting polyamide.
