FIELD: polymers, chemical technology. SUBSTANCE: invention relates to method of production of powders from modified polytetrafluoroethylenes which are used for further extrusion to obtain fettlings, pipies, hoses and strips. Nonfriable nondusting formed powders with filled weight value at least 450 g/l are made from suspension polymerizate with monomeric tetrafluoroethylene links and 0.01-1 weight % of monomeric links of at least perfluoroalkylvinyl ester with C1-C4-alkyl group by grinding polymeric particles to mean size d50 = 10-50 mcm and agglomeration in water to mean agglomerate particle size d50 = 30-100 mcm. Invention provides to obtain nonfriable formed powder exhibiting advantages in treatment, high filled weight value and absence of dust in blank making. EFFECT: improved method of producing, enhanced quality and properties. 8 cl, 6 tbl, 12 ex
