| titleOfInvention | The production method of low acetaldehyde titanium polyester |
| abstract | The present invention relates to the production method of a kind of low acetaldehyde titanium polyester, mainly solve polyester solid phase polymerization speed prepared by conventional Titanium series catalyst relatively slow, the problem that acetaldehyde residual volume is higher.The present invention is first prepared polyester by Titanium series catalyst by using, add alkali metal carboxylate compound G and at least one metallic compound H being selected from the periodic table of elements in IIA, IB, IIB, VIIB, VIII the most after completion of the esterification reaction, product after being completed by melt polycondensation again carries out solid-phase polymerization under conditions of suitable temperature and pressure, obtain the technical scheme of the polyester product of high molecular and viscosity further, preferably resolve this problem, can be used in the commercial production of polyester. |
