PERFLUOROPOLYESTER CARBOXYLIC ACID ALLYLAMIDES AS MODIFYING AGENTS OF FLUORO-RUBBER-BASE RUBBER MIXTURES Russian patent published in 2003 - IPC

Abstract RU 2203886 C1

FIELD: organic chemistry, rubber industry. SUBSTANCE: invention relates to derivatives of perfluoropolyester carboxylic acid of the formula (I) where n = 0-1; m = 1-20; R_F is fluorine atom or CF₃; is CF₃ or C₃F₇. These compounds are available synthetically, stable in room temperature and contain low level of fluoro-organic compounds with double bonds. Owing to these properties these compounds are used as modifying agents of fluoro-rubber-base rubber mixtures. EFFECT: valuable properties of compounds. 1 cl, 5 tbl, 9 ex
