Abstract
PURPOSE: To provide a high-rigidity nylon 6 which has a good property of nylon 6 by polymerizing ε-caprolactam in the presence of Ba compound and Al compound which are soluble in a polymerization system.
CONSTITUTION: ε-Caprolactam or ε-aminocaproic acid is polymerized in the presence of proper amounts of Al compound, such as Al salt of carboxylic acids like aluminum stearate, AlBO3, or Al(OH)3, and Ba compound, such as Ba salt of carboxylic acids like barium stearate, BaO, or Ba(OH). Poly-ε-caprolactam (nylon 6) which is prepared by this method has an excellent mechanical property and its tensile yield strength and modulus of elasticity in bending are improved to the level of those of nylon 66 or higher.
