Polycarbonates with pendant functional groups have attracted much attention due to their capability for further chem. modification and post-polymerization This work describes the synthesis of a poly(carbonate-co-ether) with massive pendant acrylate groups from the copolymerization of glycidyl methacrylate (GMA) with carbon dioxide (CO2), using a nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co(III) DMCC) catalyst. The carbonate linkage content (FCO2) of the poly(carbonate-co-ether) could be varied from 42.2 to 68.0% by changing the polymerization conditions. Of importance, 4-methoxyphenol was applied for regulating the copolymerization It could not only act as an inhibitor for completely depressing the self-polymerization of GMA via free radical polymerization of the double bond, but also modulate the mol. weight of the resultant copolymers. The obtained copolymer had two terminal hydroxyl groups, which were confirmed by the electrospray ionization-tandem mass spectrometry (ESI-MS) technique. A new thermoset with high glass transition temperature (Tg: 105 or 120 °C) and massive carbonate units as well as hydroxyl (or carboxylic) groups was prepared by the curing reaction of the GMA-CO2 copolymer with allyl alc. or acrylic acid in the presence of 2,2′-azobisisobutyronitrile (AIBN). In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Category: dioxole).
(2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Category: dioxole
