Nylon is a synthetic fiber having the oldest history, and the polymer is connected by the amide bond. Among them, nylon4 is obtained by the ring opening polymerization of 2-pyrrolidinone, and it has advantages including the excellent modulus and high crease-resistance. But nylon4 has critical problem of low thermal decomposition temperature(Td) which is lower than melting point(mp). Presently, the research that it supplements the low Td of the nylon4 through the copolymerization including 2-pyrrolidinone, β-lactam, ε-caprolactam, 12-amino-dodecanoicacilactam, and etc. was progressed. And the 2-pyrrolidinone and ε-caprolactam were used in this research. In this study, the monomer reactivity ratio was irradiated through the copolymerization of 2-pyrrolidone and ε-caprolactam. The moment composition of the copolymer according to the conversion ratio and accumulated average composition was predicted from the obtained monomer reactivity ratio. 2-pyrrolidinone with ε-caprolactam copolymer was synthesized by anionic ring-opening polymerization and the thermal property was observed by DSC and TGA. The potassium tert-butoxide was used as an initiator and the N-acetyl-ε-caprolactam was used as the activation reagent.
