Abstract
Reversible unstoichiometric polycondensation of a diol formate and dicarboxylic acid ester through an ester–ester exchange reaction is an effective strategy for the synthesis of telechelic polymers free from contamination with cyclic polymers.

Abstract
While the synthesis of linear polymers with both ends conserved is severely impeded due to the inevitable macrocyclization in step-growth polymerization, this work provides a new idea to mainly formation of linear polymer chains.
