Abstract
Nylon 6 was methoxymethylated to different extents for the purpose of obtaining copolymers. With these samples, the melting temperatures were measured as a function of the mole fraction of methoxymethylated units in the copolymers. The results were examined on the basis of the theoretical treatments on melting of two component copolymers proposed by the authors.3-5 It was pointed out that the melting of nylon 6 methoxymethylated to different extents behaved like that of non-isomorphic random polycaproamide copolymer copolymerized from two monomers. Thus, the quantitative relation (hx<hu) between the heat of fusion (hu) per structural unit and the heat of transition (hx) per structural unit due to quasi-crystals in the amorphous regions, and the numerical value of the constant “a” (in Eq. (1)) changing depending on the types of major component in two component copolymers were estimated for the methoxymethylated nylon 6.Keywords
