Copolymer gels of versatile morphological, mechanical, thermoresponsive properties form by free radical polymerizations of different compositions of N-isopropylacrylamide and N-ethylacrylamide in 1:1 methanol–water (v/v) mixtures. Porosities and roughnesses of the gels gradually increase with the increase in N-isopropylacrylamide loading in the system. At the same time, Young's modulus and lower critical solution temperature gradually decrease with the increase in the same.

Well-defined tadpole copolymers with polyethylene head and polystyrene tail are synthesized by combining polyhomologation, atom transfer radical polymerization, and Glaser coupling. The OH of the 3-miktoarm stars are transformed to alkyne groups, followed by Glaser cyclization and removal of the unreacted miktoarms. The characterization of the precursors, final, and hydrolyzed products by size exclusion chromatography and 1H NMR confirms the tadpole topology.
- Study of the Effects of Intramolecular and Intermolecular Hydrogen-Bonding Systems on the Polymerization of Amide-Containing Benzoxazines

Important changes in the polymerization temperatures, resulting glass transition of the polymers, and propagation rates are influenced by the nature of the hydrogen bonds of each isomer studied in this work. Furthermore, the unusually strong character of the intermolecular hydrogen bonding system present in the para isomer is uncovered and studied in details.
- Preparation of Monodisperse Hyper-Crosslinking Polymer Nanoparticles for Highly Efficient CO2 Adsorption
Caiyun Cai, Zhilin Hou, Tong Huang, Ke Li, Yannan Liu, Ning Fu, Sheng Han and Yongfeng Zhou
Version of Record online: 10 FEB 2017 | DOI: 10.1002/macp.201700001
In this paper a combined method of vesicle bilayer templating and hyper-crosslinking to prepare monodisperse microporous polymer nanoparticles with a small size of 61 nm, a high Brunauere–Emmette–Teller surface area up to ≈1300 m2 g−1, and a very high micropore surface area above 1000 m2 g−1 is reported. It also shows the best CO2 uptake property among “Davankov Resins.”
- Synthesis of Functional Poly(ε-caprolactone)s via Living Ring-Opening Polymerization of ε-Caprolactone Using Functionalized Aluminum Alkoxides as Initiators

Aluminum compounds modified by unsaturated alcohol, Me3−nAl(O(CH2)4OCHCH2)n (n = 1 (1), 2 (2), 3 (3)), initiate living ring-opening polymerization of ε-caprolactone in bulk to afford polyesters with controlled molecular weight (Mn up to 35 000 g mol−1) and high chain-end functionality (>85%), which then used for the synthesis of graft copolymers.
