    摘要： A process to prepare a cyclic polyester oligonner composition comprising a cyclic polyester oligomer having furanic units is disclosed. The process comprises the step of reacting a monomer component in the presence of an optional catalyst and/or optional organic base in a ring closing oligomerization step under conditions of a reaction temperature and reaction time sufficient to yield a cyclic polyester oligomer having furanic units. The invention further relates to a cyclic polyester oligomer composition obtainable by said process, wherein the cyclic polyester oligomer composition comprises a cyclic polyester oligomer of structure Y1 or Y2 having furanic units, wherein the composition contains less than 5 %, preferably 3, most preferably 1 weight % of linear oligomeric polyester species in the composition. The present invention further relates also to the use of said cyclic polyester oligomer composition in the production of a polyester polymer.
