    Abstract: The refillable polyester bottle of the invention has a mean crystallinity of 32 to 70 % at the bottle body, a methanol adsorption of 1,500 ppm or less at the same portion and a paraxylene adsorption of 300 ppm or less at the same portion. Therefore, the bottle is excellent in non-adsorptivity and heat resistance. According to the method of removing adsorbates on a polyester bottle of the invention, the adsorbates can be rapidly desorbed by holding the bottle in air of 40 to 150 DEG C or bringing the bottle into contact with water or water vapor heated at 40 to 150 DEG C.

    Abstract: A bottle molded from a polyester composition comprising 97 to 99.99% by weight of a polyester and 3 o 0.01% by weight of a polyester elastomer, which bottle exhibits dimensional change ratios of not greater than 5% measured in the height direction of the bottle and also not greater than 5% measured in the wall part diameter direction of the bottle and has an overturning angle of at least 10.degree., when the bottle was subjected to a hot bath test in which the bottle is filled with a beverage containing 2.5 gas volume carbon dioxide at 23.degree.C, stoppered and immersed in sealed condition in a hot bath heated at 70.degree.C. Thus, the bottle retains self-standing property without deformation even after it is filled with a carbonated beverage and subjected to heat sterilization.

    Abstract: The first lubricating oil composition of the present invention is a composition comprising a polycarbonate represented by the following general formula, at least one compound as an essential component selected from the group consisting of epoxy compounds, phenol compounds, sulfur compounds and amine compounds, and a triester phosphite compound and a triester phosphate compound as an optical component. R1OCOOÄ(R2O)pCOOÜnR3 wherein R1 and R3 are each independently a specific hydrocarbon group or a specific hydrocarbon group containing an ether bond, R2 is a specific alkylene group, and p and n are specific integers. The lubricating oil compositions are excellent in lubricating properties, cleaning properties and electrical insulating properties, and their viscosity at low temperature can readily be lowered and, in addition thereto, generation of carbon dioxide gas can be inhibited.
