Summary:FIELD: polymer compositions on base of concentrated aqueous dispersions of fluorine-containing copolymers, namely tetrafluoro-ethylene with hexafluoroprolilene or with perfluoropropylene vinyl ether for obtaining various coats and polyimide fluoroplastic films used for high heat-resistant insulation of wires. ^ SUBSTANCE: proposed composition is made in form of concentrated aqueous dispersion at the following ratio of components, mass-%: tetrafluoro-ethylene copolymer with hexafluoroprolilene or with perfluoropropyl vinyl ether, 50-55; fluoroemulsifier, 0.1-0.5; stabilizing non-ionogenous surfactant, 4-8, preferably 5-7 (relative to fluoro-copolymer) which is just mixture of polyethylene glycol ethers of monoalkyl phenols on base of trimers of propylene of the following formula: R-C6H4O-(CH2CH2O)nH where R is alkyl radical isonnonyl-C9H19 added to phenol in para-position relative to hydroxyl group and n is averaged number of moles of ethylene oxide added to one mole of alkyl phenols equal to 9-12 and water. Composition for enhancing the stabilization at storage may additionally contain aqueous ammonia solution in the amount sufficient for obtaining pH equal to 5.0-10.5. ^ EFFECT: improved service and physico-chemical properties of coat. ^ 3 cl, 2 tbl
