Selective production of poly(carbonate-co-ether) over cyclic carbonate for epichlorohydrin and CO2 copolymerization via heterogeneous catalysis of Zn-Co (III) double metal cyanide complex
Epichlorohydrin (ECH), as a cheap raw chemical material, is an ideal monomer for copolymerization with CO2 to produce biodegradable polycarbonates. This work describes the selective ECH-CO2 copolymerization via heterogeneous catalysis of nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co (III) DMCC), affording a poly(carbonate-co-ether) with carbonate content up to 70.7%. Remarkably, t...

Collapse and Swelling of Poly(N-isopropylacrylamide-co-sodium acrylate) Copolymer Brushes Grafted on a Flat SiO2 Surface
关键字：pnipam brush, qcm
Poly(N-isopropylacrylamide-co-sodium acrylate) copolymer brushes grafted on SiO2-coated quartz crystal surface were prepared with a surface-immobilized initiator. The collapse and swelling of the thermally sensitive copolymer brushes in water were studied with quartz crystal microbalance in situ. The frequency and dissipation changes with the temperature increasing in the ran...

VISCOELASTICITY OF CROSSLINKED POLY(ETHYLENE-CO-PROPYLENE) COMPOSITES
关键字：VISCOELASTICITY,CROSSLINKED,POLY,ETHYLENE,PROPYLENE,COMPOSITES,
Elastomers exhibit an instantaneous, reversible strain when subjected to a stress. Real elastomers show some unrecovered strain or creep since all molecules must not be included in the network structure. If crosslinking is increased&nb...
