    摘要: The invention relates to a method of preparing wholly aromatic polyester including: mixing monomers, introducing the mixed monomers into a reactor having a rectangular or trapezoidal plate type stirring impeller, and polymerizing the introduced monomers through esterification with a power per unit volume of 10~60 kW/m3, a length (L) to diameter (D) ratio of the stirring impeller is 1~3:1, and a distance between the bottom of the reactor and a lower portion of the stirring impeller is 1/100~ 1/15 times of the diameter (D); b) pulverizing the obtained polymer; and c) solid state polymerizing the pulverized polymer. The present invention also relates to a method of preparing wholly aromatic polyester having excellent heat resistant properties in which byproduct is effectively discharged by controlling a heating rate and reaction holding time between the weight loss initiating temperature and the melting point of a low molecular weight polymer generated in a melt polymerization in a solid state polymerization, adhesion does not occur, and discoloration due to heating does not occur.

    摘要: A copolyester consisting essentially of ethylene terephthalate units and further comprising 0.01 to 1 mole % based on the sum of the moles of total diol units and the moles of triol units of a triol unit represented by the following formula (I) and/or a triol unit represented by the following formula (II).


    wherein A is a group represented by formula -CH 2 CH 2 - or formula -CH(CH 3 )CH 2 -, B is a divalent hydrocarbon group, -CO-, -SO 2 -, -O- or a direct bond (-), and p, q, r, s, t and u are each an integer of 1 to 8. A process for producing the same and molded articles (in particular extrusion blow molded articles) therefrom. The copolyesters of the present invention are applicable to melt moldings accompanying melt extrusion, in particular extrusion blow molding, where parisons therefrom have good draw-down tendency and blow moldability. The copolyesters can give, without causing troubles on molding, molded articles, in particular extrusion blow molded articles, having excellent transparency, heat resistance, moisture resistance and like properties. Aromatic triols usable for producing the above copolyesters are also provided.
