Abstract
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.
