| titleOfInvention | Titanium series polyester catalyst and the method for producing semi-dull polyester |
| abstract | The present invention relates to a kind of method of titanium series polyester catalyst and production semi-dull polyester, the dibastic alcohol compound catalyst hydrolytic resistance that mainly solves to exist in the prior art obtained titanium is poor, solubility is low in ethylene glycol, the problem of obtained semi-dull hue of PET chip difference.The present invention is by using with titanium compound, dihydric alcohol and reaction product selected from least one of II B of A, V of the periodic table of elements II, II B metal salt compound, at least one aliphatic organic acid and at least one phosphate compound are catalyst, catalyst preparation pH value of reaction system is kept preferably to solve the problem for 4.5~6.5 technical scheme simultaneously, available in the polyester particularly industrial production of semi-dull polyester. |
