Carbon dioxide (CO 2 ) as a direct material was copolymerized with epoxides to synthesize new aliphatic polycarbonates, and the copolymerization was catalyzed by the coordinate catalyst composed of rare earth yttrium phosphonate and triisobutylaluminum [Y(P 204 ) 3 -A1(i-Bu) 3 ]. The epoxides used in this research included epichlorohydrin (ECH) and some new glycidol ether (GE) monomers prepared by the reaction of ECH and phenol or alcohol, such as ␣-allyl glycidol ether, ␤-chloroethyl glycidol ether, benzene glycidol ether, m-tolyl glycidol ether, and benzyl glycidol ether. The copolymers were characterized by infrared (IR), 1 H nuclear magnetic resonance (-NMR), and dynamic mechanical analysis. The results show that Y(P 204 ) 3 -A1(i-Bu) 3 had better catalytic activity in the copolymerization of CO 2 with epoxide, and the copolymerization rate of aryl GE was distinctly higher than that of aliphatic GE. Dynamic mechanical analysis indicated the glass transition temperature T g of the copolymers GE-CO 2 were lower than that of ECH-CO 2 .

“…One possible utilization approach is to produce polymeric materials from CO, resources and use them in daily life and industry, even though the production of polymers perhaps consumes CO, in a relatively small amount with respect to the amount produced by burning fossil fuels. Since poly(prow1ene carbonate) (PPC) from CO, and propylene oxide (PO) was first synthesized in 1969, the copolymerization of CO, with cyclic ethers has been widely studied by several research groups (8)(9)(10)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28). CO, is relatively stable so that its copolymerization with cyclic ethers needs a highly active catalyst.…”

Various zinc dicarboxylate catalysts were synthesized by the reaction of zinc oxide with eleven different glutaric acid derivatives, and their coordination characteristics were investigated by infrared spectroscopy. The electronic nature and steric hinderance of substituents influenced the coordination of the carboxylate and the zinc metal ion. The coordination characteristics were classified into three categories: i) compounds exhibiting bridging bidentate coordinating bonding modes, such as syn-anti and syn-syn bridging: ii) compounds with only unidentate coordination: and iii) compounds with mixed coordinations of unidentate and

“…Polyesters are macromolecules, which are linked by ester groups by way of condensation polymerization. A waterborne polyester is rich in water soluble groups in the macromolecule chain, so that it can dissolve or disperse in water to form an aqueous solution or dispersion . At present, waterborne polyesters can be roughly classified into three categories according to the type of hydrophilic units.…”

Isophorone diisocyanate was used as a chain extender to coupling the soft segment water-borne polyester with the hard segment water-borne polyester, to overcome the disadvantages of low molar mass and poor mechanical properties of waterborne sulfonatecontaining polyesters. The molecular structure of the extended polyester was confirmed by FTIR and 1 H NMR, and the increased molar mass of the resultant was characterized by SEC. The extended products could be dispersed in water with the emulsion particle size less than 50 nm in diameter, slightly larger than that of precursors of soft-and hard-segment polyesters. The emulsion viscosity of polyesters after the chain extension was lower when the emulsion concentration was not larger than 25 wt%, which is conducive to the spraying application of the polyester for coating. DSC analysis indicated that the polyester after chain extension had two different glass temperatures, suggesting that the polyester bulk had a microphase separation structure. The mechanical performance of the coupled polyester manifested an obviously improved elongation at break and had a feature of higher elastic recovery rate. The results of this study indicate that the chain extension is an effective method to increase the molar mass and improve mechanical properties of waterborne polyesters.
