Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: composition is obtained through hydrolysis of a mixture of oligomeric products of photo-oxidation of hexafluoropropylene containing 60-90 wt % acid fluoride of perfluoropolyoxaalkyl carboxylic acid and 10-40 wt % perfluoropolyoxaalkyl ketone. The composition contains from 10 to 40% perfluoropolyoxaalkyl dihydroxides of general formula (I): , where: n=10-40; m=0-10; l=0-1; x=1-3, and from 90 to 60% perfluoropolyoxaalkyl carboxylic acid of general formula (II): where: n=10-40; m=0-10; l=0-1; x=1-3. A coating on a substrate is obtained using this composition. The composition is used as a lubricant. ^ EFFECT: optimum combination of antifriction, anti-adhesion and anticorrosion properties. ^ 3 cl, 16 ex, 3 tbl Изобретение относится к антифрикционной композиции, используемой для получения покрытий и смазок. Композицию получают гидролизом смеси олигомерных продуктов фотоокисления гексафторпропилена, содержащей 60-90 мас.% фторангидрида перфторполиоксаалкилкарбоновой кислоты и 10-40 мас.% перфторполиоксаалкилкетона. Композиция содержит от 10 до 40% перфторполиоксаалкилдигидроксидов общей формулы (I): ! ! где n=10-40; m=0-10; l=0-1; х-1-3, и от 90 до 60% перфторполиоксаалкилкарбоновых кислот общей формулы (II): ! ! где n=10-40; m=0-10; l=0-1; x=1-3. С использованием этой композиции получают покрытия на субстрате. Композицию применяют и в качестве смазки. Композиция обеспечивает оптимальное сочетание антифрикционных, антиадгезионных и антикоррозионных свойств. 3 н. и 23 з.п. ф-лы, 3 табл.
