제목 Transesterification in Copolyetherester Blends
초록 Segmented block copolyetheresters have the hard segments that can cause transesterification. Ester interchange reactions are found in some polyester blends, which cause randomizing effect. The PBT/PBN copolymer can cocrystallize and show the isodimorphic crystallization against copolymer composition. Copolyetherester blend composed of cocrystallizable hard segments will show the melting endotherm.
We blended the copolyetheresters having PBN or PBT hard segment together in solution and examined the influence of transesterification. Blending with the same hard segment content and time affected the sequence distribution and melting behavior. We compared the blend which showed ester interchange reaction with the random copolymer.
