| 英文摘要 | A complete study on the catalytic activity of stannous oxalate for poly(trimethylene terephthalate) (ptt) synthesis via esterification method is carried out by comparison to the well known catalysts (tetrabutyl titanate (tbt), dibutyltin oxide (bu2sno), and stannous octoate (soc)). their catalytic activity in the esterification process is monitored by measuring the amount of water generated, while intrinsic viscosity (iv) and content of terminal carboxyl groups (ctcg) are used as the index in the polycondensation process. stannous oxalate shows higher activity than the other catalysts. decrease in reaction time and improvements in ptt property are observed. the higher catalytic activity of stannous oxalate is attributed to its chelate molecular structure. |
