Well-defined allyl-functional poly(carbonate)s were synthesized via the organocatalytic ring-opening polymerization of 5-methyl-5-allyloxycarbonyl-1,3- dioxan-2-one using the dual 1-(3,5-bis(trifluoromethyl)phenyl)-3- cyclohexylthiourea and (-)-sparteine catalyst system. The resulting allyl-functional poly(carbonate)s obtained showed low polydispersities and high end-group fidelity, with the versatility of the system being demonstrated by the synthesis of block copolymers and telechelic polymers. Further functionalization of homopolymers with degrees of polymerization of 11 and 100 were realized via the radical addition of thiols to the pendant allyl functional groups, resulting in a range of functional aliphatic poly(carbonate)s.

Since extraction of the naturally occurring mussel-foot proteins is expensive and time-consuming, routes towards synthetic analogues are continuously being explored. Often, these methods involve several protection and deprotection steps, making the synthe

A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl ester group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl ester group. Using a suitable nucleophile, the pendant pentafluorophenyl ester group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.
