New hydroxyl polyesters fluid at room temperature, with low viscosities at relatively high molecular weight and very low setting points have alkyl side chains in substantially regular arrangement along preferably unbranched or only slightly branched polyester chains, and are formed by the reaction of monocarboxylic acids and/or monoalkanols or their esters of ethers or polyester building components with additional polyester-forming derivatives. The new polyesters can be used to special advantage, after functionalization, for coatings or as adhesives. Especially advantageous is the fact that they can be used without solvents or with a very low solvent content.
