英文摘要 | Monomer-casting polyamide 6 (mcpa6)/polymethacrylic ionomer blends were synthesized by the in situ anionic ring-opening polymerization of e-caprolactam. the polymethacrylic ionomer used in this study was a copolymer of methyl methacrylate and sodium or zinc methacrylate. because the polymethacrylic ionomer strongly interacted with polyamide 6 (pa6) chains, it influenced the alignment of the polyamide chains. the change in the degree of the order of hydrogen bonding in mcpa6 caused by the addition of the polymethacrylic ionomer was studied with fourier transform infrared. the change in the interaction between pa6 chains was studied with rheological measurements. the influence of the polymethacrylic ionomer on the crystallization behavior of mcpa6 was also studied with differential scanning calorimetry. the isothermal crystallization and subsequent melting behavior were investigated at the designated temperature. the commonly used avrami equation was used to fit the primary stage of the isothermal crystallization. the avrami exponent (n) values were evaluated to be 2 < n < 3 for the neat mcpa6 and mcpa6/polymethacrylic ionomer blends. the polymethacrylic ionomer, acting as a stumbling-block agent in the blends, decelerated the crystallization rate with the half-time of crystallization increasing. the polymethacrylic ionomer made the molecular chains of mcpa6 more difficult to crystallize during the isothermal crystallization process. more less perfect crystals formed in the mcpa6/polymethacrylic ionomer blends because of the interaction between the mcpa6 molecular chains and polymethacrylic ionomer. the crystallinity of the blends was depressed by the addition of the polymethacrylic ionomer. the thermal stability was also studied with thermogravimetric analysis.
