The present invention relates to a process for the preparation of an ester from a polyol which is solid at 25° C. and a carboxylic acid component which contains at least 50 wt. % of at least one mono- or polyunsaturated aliphatic carboxylic acid, based on the total weight of the carboxylic acid component, in a reactor under reduced pressure. The invention also provides a device, a process for the preparation of a thermoplastic composition comprising the ester prepared according to the invention, a process for the production of a shaped article comprising the ester according to the invention or the thermoplastic composition according to the invention, a process for the production of a packed product, a process for the production of an at least partly coated object, and uses of the esters according to the invention as an additive in various compositions.
