METHOD FOR PRODUCING POLYAMIDE RESIN |
摘要 |
A method for producing a polyamide resin characterized by comprising thermally polycondension of tetramethylene diamine and either an aliphatic dicarboxylic acid having 7 or more carbon atoms or a salt thereof, and then being melt-polymerized at a temperature equal to or higher than the melting point thereof until the relative viscosity of a 0.01 g/ml solution thereof in 98% sulfuric acid solution with a 0.01 g/ml content at 25° C. becomes 2.2-5.0.
