Abstract: A process to prepare a (iv) cyclic polyester oligomer composition comprising a cyclic polyester oligomer having furanic units and two to five repeat units is disclosed. The process comprises the steps of: (a) reacting a monomer composition comprising: (i) a bifunctional furan-derivative and (ii) a diol in an linear oligomerization step to produce a (iii) linear oligomer composition comprising a linear oligomer species, (b) reacting the (iii) linear oligomer composition in a distillation-assisted cyclization (DA-C) step to form a (iv) cyclic polyester oligomer composition and a (v) diol byproduct, wherein the (v) diol byproduct is removed by evaporation in the distillation-assisted cyclization (DA-C) step.

Abstract: 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.
