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.
