| titleOfInvention | The production method of the polyester of titanium catalysis |
| abstract | The present invention relates to a kind of production method of polyester of titanium catalysis, slow, the poor problem of form and aspect of solid phase speed while mainly solving in the past Titanium series catalyst preparation bottle level polyester. The present invention is by adopting Titanium series catalyst, make dicarboxylic acids and dihydroxylic alcohols under suitable temperature and pressure, carry out esterification, obtain prepolymer, then carry out melt polycondensation reaction and obtain polyester product, product after melt polycondensation completes carries out solid-phase polymerization under the condition of suitable temperature and pressure, before esterification or after esterification, add at least one technical scheme as co-catalyst in compound G, the alkali metal compound H of sulfonic acid or sulfonate, preferably resolve this problem, can be used in the industrial production of polyester. |
