摘要： Disclosed is a copolyester resin composed mainly of terephthalic acid, ethyleneglycol, 1,4-cyclohexanedimethanol, polyethyleneglycol bisphenol-A and a multifunctional monomer. According to the current invention, the multifunctional monomer and polyethyleneglycol bisphenol-A are additionally copolymerized along with 1,4-cyclohexanedimethanol, whereby the resultant copolyester resin can have low haze and high melt viscosity and melt strength, with superior moldability due to low melt pressure. In addition, extrusion blow molded articles and profile extruded articles, such as bottles and tubes, are provided by use of the copolyester resin having superior properties.

摘要： Disclosed is a method for preparing polyester resins copolymerized with glycol for modification such as 1,4-cyclohexanedimethanol, in which the content of said glycol ingredient for modification ranges from 20 to 80 mol % of the total glycol content. Dicarboxylic acid such as terephthalic acid is esterified with ethylene glycol and said glycol for modification. The esterification product is subjected to polycondensation in the presence of a titanium dioxide/silicon dioxide coprecipitate catalyst, said catalyst being in the form of 4% or less strength by weight suspension in glycol. The copolyester prepared as above shows excellent transparency and color properties in addition to being produced at high efficiency.
