FIELD: chemistry.
SUBSTANCE: invention relates to novel polydimethylmethyl(hexafluoroalkyl)-siloxanes, which can be used as a base for heat-, oil- and petrol-resistant materials for an application in different fields of industry. Claimed are polydimethymethyl-(2'-(2,3,3-trifluoro-2-trifluoromethylcyclobutyl)ethyl)siloxanes of formula I
where Rf is 
n=99-30, m=1-70, 1=3-15, for the heat-, oil- and petrol-resistant materials.
EFFECT: claimed polymers possess high heat-, oil- and petrol-resistance and are vulcanisable at room temperature.
