主　　题：Tetra(acetylacetonato) tin(Ⅳ) Polytrimethylene terephthalate Terephthalic acid 1,3-Propanediol 

摘      要：Chelate tetra(acetylacetonato) tin(Ⅳ) was prepared and used as catalyst for polytrimethylene terephthalate *** exhibited higher catalytic activity than tetrabutyl titanate,butyltinhydroxide oxide and dibutyltin *** in reaction time, content of terminal carboxyl group,color intensity and increase in intrinsic viscosity were *** unique molecular structure can be considered as factor remarkably improving the catalytic activity of tetra(acetylacetonato) tin(Ⅳ).
