Abstract: PURPOSE:To improve especially thermal aging resistance and durability, by a method wherein a tubular molded body such as a tube or a hose superior in mechanical and sliding properties at the time of a high temperature is manufactured by molding copolymer polyester containing a structural unit expressed by a specific formula. CONSTITUTION:This tubular molded body is made into a molded product of copolymer polyester comprised of a structural unit of polyester formed of p- hydroxybenzoic acid expressed by a formula I, a structural unit formed of 4, 4-dihydroxy biphenyl expressed by a formula II, a structural unit formed of ethylene glycol expressed by a formula III and a structural unit formed of terephthalic acid expressed by a formula IV. On this occasion, the structural units (I+II) and (I+II+III) are made respectively 80-93mol% of the (I+II+III) and 20-7mol% of the (I+II+III). Then a matter whose mol ratio of the structural unit I/III becomes 78/22-93/7 and logarithmic viscosity becomes 1.0-3.0dl/g is used as the copolymer polyester.

Abstract: PURPOSE:To obtain the subject melt moldable resin, having units derived from phenylhydroquinone, units derived from diphenyldicarboxylic acid and units derived from naphthalenedicarboxylic acid and excellent in mechanical and thermal characteristics. CONSTITUTION:The objective resin is composed of structural units expressed by formulas I to IV (X is formulas V, VI, etc.) at (10/0)-(2/8) molar ratio of the units expressed by formulas (I/II) and (8/2)-(3/7) molar ratio of the units expressed by formulas (III/IV) in equimolar amounts of the units expressed by formulas (I f II) and units expressed by formulas (III + IV). The aforementioned resin has 0.4-20dl/g inherent viscosity measured at 0.1g/dl concentration in pentafluorophenol at 60 deg.C and is preferably obtained by respectively using phenylhydroquinone, etc., as a raw material for the units expressed by formula I, methylhydroquinone, etc., as a raw material for the units expressed by formula II, 4,4'-diphenyldicarboxylic acid as a raw material for the units expressed by formula III and 2,6-naphthalenedicarboxylic acid as a raw material for the units expressed by formula IV and subjecting the above-mentioned raw materials to deacetylation and polycondensing reaction.
