実験手順
A mixture of 1734 parts by weight of terephthalic acid and 713 parts by weight of ethylene glycol was stirred for 4 hours under 2 atmospheres. Thereafter, 0.3 part by weight of germanium dioxide, 0.3 part by weight of tetraethylammonium hydroxide and 0.4 part by weight of methyl acid phosphate were added, and the reaction was carried out at 260° C. for 2 hours under 1 atmosphere. The reaction product was withdrawn, cooled, pulverized and dried to obtain 1500 parts by weight of an ethylene terephthalate oligomer.
