Poly(β-amino esters) polymers, a promising class of biomaterials, were found to degrade in alcohol via transesterification. This effect was found to be dependent upon the presence of free amine groups in the polymer backbone. Using this reactivity, it was also shown it is possible to modify the gels with alcohol containing drug molecules, creating a pro-drug gel system.

Molybdenum imido alkylidene N-heterocyclic carbene (NHC) complexes as room temperature-latent precatalysts for the ring-opening metathesis polymerization (ROMP) of dicyclopentadiene are described. Precatalysts are tailored by combining strongly and weakly σ-donating NHCs with suitable anionic ligands at molybdenum such as triflate and t-butoxide. All precatalysts prepared offer access to cross-linked poly-DCPD though with different degrees of cross-linking and glass-transition temperatures.

Three acid catalysts and several polymerization conditions were evaluated in the CROP of TMC over a tri-functional initiator, TMP. Features of the obtained polymers were characterized by NMR, GPC, and MALDI. MALDI was found an essential characterization technique to detect two polymers produced by two competitive mechanisms, which are usually overlooked when branched polymers are targeted. Metal-free polymers with low Đ value and well-known chemical structure and composition were synthesized, which can be further used as polymeric matrix for coating preparation or in the biomedical or pharmacological field.
- Dual-responsive crosslinked micelles of a multifunctional graft copolymer for drug delivery applications (pages 1536–1546)

A novel micelle with pH and reduction dual sensitivity formed based on a welldefined multifunctional amphiphilic graft copolymer P[Asp(MEA)-r-Asp(PEG)-r-Asp(PDEAEMA)-r-Asp(HMTPA)] was developed. Drug leakage can be avoided in micelle storage and significantly reduced in blood circulation, whereas a burst release of drug was triggered in an acidic and reductant-enriched environment such as in lysosomes. Cell studies revealed this polymer and its micelles are promising candidates for drug delivery applications.

Chemical warfare agents continue to post a threat to civilians and military personnel in conflict zones. As a step toward a breathable hybrid fabric that provides on-demand protection against these agents, the authors have synthesized a triarylmethanol-containing responsive polymer-substituted nanoparticle using surface-initiated ring-opening metathesis polymerization. Using this nanocomposite as a platform demonstrates a tunable chain collapsing response upon exposure to agent simulants, which is the key to the proposed protecting scheme.
