Abstract A process for the synthesis of vinyl esters from butene oligomers, wherein butenes are oligomerized, the butene oligomers are separated from the oligomerized mixture, the butene oligomers are converted to carboxylic acids which are longer by one carbon atom, and the resulting carboxylic acids are converted to the corresponding vinyl esters. The butene oligomers are in particular dibutene, tributene and tetrabutene. The invention also relates to the use of the vinyl esters as plasticizers or as comonomers in polymerization reactions.
