FIELD: varnish-and-paint industry. SUBSTANCE: associated thickeners for the use in film-forming paint compositions represent water-soluble poly(acetal or ketal ethers) blocked by hydrophobic groups at their ends, which are prepared by copolymerization of alpha-, omega-, diol-, ditriol-, or diamino-polyether with a hem-dihalogen compound in presence of base to form alpha-, omega-, diol-, ditriol-, or diaminopoly(acetal or ketal ether), which is then brought into reaction with hydrophobic compounds to give final product. EFFECT: improved following properties of paints: stability, flowability and leveling, film formation, resistance to sputtering and leaks. 37 cl, 5 tbl, 34 ex
