폴리트리메틸렌 테레프탈레이트 / 폴리에틸렌 나프탈레이트 용융 블렌드
나상권,김정규,홍완해 한국공업화학회 2000 응용화학 Vol.4 No.1
Melt blends of poly(trimethylene terephthalate)(PTT) and poly(ethylene 2,6-naphthalate)(PEN) with various compositions were prepared at 275℃ using 40rpm for various mixing times. Transesterification and misibility of blends of PTT with PEN was studied by dynamic mechanical thermal analysis(DMTA) and NMR.
폴리트리메틸렌텔레프탈레이트 / 폴리비스페놀카보네이트 용융 블렌드 (1)
나상권,김정규,홍완해 한국공업화학회 2000 응용화학 Vol.4 No.2
Melt blends of poly(trimethylene terephthalate), PTT and Poly(Bisphenol A carbonate), PC with various compositions were prepared at 275℃ using 40rpm for 60min. Thermal properties of PTT/PC blends have been studied by differential scanning calorimetry(DSC) and dynamic mechanical thermal analysis(DMTA). The glass transition temperatures of blends increased as the amount of PC increased. Each blend showed a single peak of tan δ in the glass transition region, suggesting that PTT and PC might be compatible.
