    摘要: An organocatalytic system, having a sulfonic acid as catalyst, for the polymerization of carbonates, and a polymerization process employing said system to obtain bio-polycarbonates devoid of ether units inserted by decarboxylation. The catalyst system for the ring-opening polymerization reaction of cyclic carbonates is formed of an initiator and, as catalyst, of a sulfonic acid of formula R′—SO3H, where R′ denotes either: a linear alkyl group including from 1 to 20 carbon atoms or a branched or cyclic alkyl group including from 3 to 20 carbon atoms, or a an aryl group.
