摘要

The rheological properties of poly (trimethylene-co- butylene terephthalate) copolymers were investigated by a capillary rheometer. It is indicated that the copolymer melt is a typical pseudoplastic fluid. The viscosity of the copolymer melt declines with the introduction and increasing of the content of PBT, at the same time, also declines with the melt temperature. The non-Newtonican index and the viscous flow activation energy of the copolymer melt are between those of the pure PTT and PBT.
