Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polyester polymerization catalyst and a polyester produced by using the same. More specifically, the present invention relates to a method for preparing a polyester from a group consisting of Cu, Ag, Au, Cd and Hg without using an antimony compound. The present invention relates to a polyester polymerization catalyst using one or more selected metal compounds, and a polyester produced using the same.

2. Description of the Related Art Polyester, especially polyethylene terephthalate (hereinafter abbreviated as PET) has excellent mechanical properties and chemical properties, and is applicable to various uses such as fibers for clothing and industrial materials, and packaging. It is applied to various films and sheets for tapes and magnetic tapes, and molded products such as bottles and engineering plastics.

[0003] In the industrial production of PET, bis (2-hydroxyethyl) terephthalate is produced by esterification or transesterification of terephthalic acid or dimethyl terephthalate with ethylene glycol. Obtained by polycondensation. As a catalyst used in the polycondensation, antimony trioxide is widely used. Antimony trioxide is a catalyst which is inexpensive and has excellent catalytic activity, but has a problem that darkening and foreign matter are generated in PET due to precipitation of metal antimony during polycondensation. In addition, environmental issues have recently raised concerns about the safety of antimony. Under these circumstances, polyesters containing no antimony have been desired.

[0004] Attempts have been made to use antimony trioxide as a polycondensation catalyst and to suppress the occurrence of blackening and foreign matter in PET. For example, in Patent No. 2666502,
The use of a compound of antimony trioxide, bismuth and selenium as a polycondensation catalyst suppresses the formation of black foreign substances in PET. Also, in JP-A-9-291141,
It is stated that the use of antimony trioxide containing sodium and iron oxides as a polycondensation catalyst suppresses the deposition of antimony metal. However, these polycondensation catalysts cannot achieve the purpose of a polyester containing no antimony after all.

[0005] Studies have been made on polycondensation catalysts that can replace antimony trioxide. In particular, tetraalkoxy titanates have already been proposed, but the PET produced therewith has problems that it is significantly colored and that thermal decomposition easily occurs.

As an attempt to overcome such problems when using tetraalkoxy titanate as a polycondensation catalyst, for example, Japanese Patent Application Laid-Open No. 55-116722 discloses that tetraalkoxy titanate is used simultaneously with cobalt salt and calcium salt. A method has been proposed. Also, JP-A-8-7358
No. 1 proposes a method in which a tetraalkoxy titanate is used simultaneously with a cobalt compound as a polycondensation catalyst and a fluorescent whitening agent is used. However, in these proposals, although the coloring of PET is reduced when tetraalkoxy titanate is used as a polycondensation catalyst,
Effective suppression of thermal decomposition of ET has not been achieved.

Germanium compounds have been put to practical use as a polycondensation catalyst which can replace antimony trioxide and which overcomes problems such as the case where tetraalkoxy titanate is used. It has a problem that it is very expensive and a problem that the catalyst concentration in the reaction system changes due to easy distilling out of the reaction system during the polymerization, making it difficult to control the polymerization.

[0008]

SUMMARY OF THE INVENTION The present invention provides a novel polycondensation catalyst other than an antimony compound, and a polyester produced using the same.

[0009]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies with the aim of solving the above problems, and found that Cu, Ag, A
Although the catalytic activity of metal compounds of u, Cd, or Hg was originally low, it was surprisingly found that the co-presence of certain additives enabled them to have sufficient activity as polycondensation catalysts. When using the polycondensation catalyst of the present invention, a catalyst such as an antimony compound is different from Cu, Ag, Au, Cd, or
A polyester of Hg metal compound catalyst can be obtained.

That is, the present invention provides a novel polyester polymerization catalyst comprising at least one metal compound selected from the group consisting of Cu, Ag, Au, Cd, and Hg, and a polyester produced by using the same. I will provide a.
