PURPOSE: A plastic tubular body that is composed of a polyesteramide consisting of specific ester units and amide units, thus showing high flexibility and keeping high heat resistance, weathering resistance, hydrolysis resistance, gas barrier properties and high transparency for a long period of time.
CONSTITUTION: A polyesteramide that is composed of 10W90pts.wt. of ester units mainly consisting of benzenedicarboxylic acid and 1,4-butanediol, preferably butylene terephthalate and/or isophthalate and 90W10pts. of amide units consisting of dodecanamide and/or undecanamide is formed into a tubular product. The above polymer is obtained by the one-step polymerization of all the monomers or the reaction between their prepolymers. Preferably, the polymer has a relative viscosity of 1.5W3.0 when measured in o-chlorophenol at 0.5% concentration at 25°C.
