초록

To achieve fast synthesis (10 minutes after injection into a mold) of polyamide 6 by anionic ring-opening polymerization of the monomer, ε-caprolactam, the effects of fabrication parameters, such as the concentration of the initiator or activator, reaction temperature, moisture content of the monomer, commercial additives to the polymerization, and properties of polyamide 6, were investigated. The polyamide 6 synthesized at a reaction temperature of 150 ℃, and an initiator or activator concentration of 2.5/1.67 wt%, showed a high reaction conversion, molecular weight, and excellent mechanical strength. Applying these parameters to the thermoplastic resin-transfer molding process led to the successful fabrication of thermoplastic carbon fiber-reinforced composites. Anionic polymerization was successful only for monomers with a moisture content of less than 200 ppm. Applying dried N2 gas to the molten ε-caprolactam effectively reduced the moisture content of ε-caprolactam, converting the humid monomers into polymerizable monomers with a low moisture content of less than 200 ppm. The effect of commercial modifiers, BRUGGOLEN® TP-C1608 and NYRIM ADDITIVE 6 plus (Bruggeman, Germany) on the thermal stability and toughness of PA6 was also investigated.
