COPOLYMERIZATION OF ETHYLENE WITH CYCLODIOLEFIN BY NON-METALLOCENE TRANSITION METAL COMPLEXES
Synthesis of polyolefins bearing pendant double bonds attracts considerable attention in the recent years. This is primarily because the pendant double bonds of the poly(olefin)s can be easily converted into functional groups by furthe...

Improving thermal stability of aliphatic polycarbonate through coordination interaction with metal stearate
Poly(propylene carbonate) (PPC), a copolymer of carbon dioxide (CO2) and propylene oxide, was first synthesized by Inoue and coworkers in 1969.1 Over the past decades, considerable attentions have been paid to the development of h...

Effect of carbon nanotubers on performances of ionic polymer-metal composite actuators
Ionic polymer membrane cast from the mixture of poly (sodium 4-styrenesulfonate-co-acrylic acid) (PSA) and polyvinyl alcohol (PVA) was used as an electromechanical actuator. Surface modified multi-walled carbon nanotubes (MWNTs) were used as&nbs...

Anionic Copolymerization of Carbonyl Sulfide with Epoxides via Alkali Metal Alkoxides
Carbonyl sulfide (COS), an analogue of carbon dioxide (CO2), can be converted to CO2 via the carbonic anhydride enzymes widely existing in nature. COS is an ideal monomer for making poly(monothiocarbonate)s, which are difficult to synthesize by traditional methods. Herein, for the first time, we describe an anionic copolymerization of COS with epoxides using alkali metal alkoxides as the catalys...

Silk fibroin/polyethylenimine functional hydrogel for metal ion adsorption and upcycling utilization
The indiscriminate disposal of heavy metal ions poses serious threat to the environment and public health. Herein, we report a sustainable and low-cost silk fibroin (SF)/polyethyleneimine (PEI) composite hydrogel for the remediation of heavy metal ions in the aqueous solutions. The SF/PEI hydrogel demonstrated excellent adsorption capacities for the Cu(II), Pb(II), Cd(II), Zn(II), Ni(II), an...

[Chem. Eur. J.] Controlled Growth of Metal-Organic Frameworks on Polymer Brushes
Polymer brushes are for the first time used to induce the synthesis of metal-organic frameworks (MOFs). The semi-fixed polymer chains provide a confined environment,
which allows a mild growth of MOFs in between polymer chains to give surface-attached spherical MOF nanoparticles, in contrast to the larger MOF cubes/plates formed simultaneously in solution. Polymer brushes bearing carboxylate ...
