    摘要: A functionalized polymer includes the reaction product of a reactive polymer and a compound that includes an aryl group having at least one directly bonded OGp substituent, where Gp is a protecting group, and a substituent (Q) which is free of active hydrogen atoms and which is, or connects to the aryl group through, a moiety that includes a carbon-to-nitrogen multiple bond. The polymer can be provided from a solution that includes one or more types of ethylenically unsaturated monomers which include at least one type of polyene, particularly one or more conjugated dienes in certain embodiments. An active terminus of the resulting reactive polymer can react with the Q substituent of the compound so as to provide a polymer having as a terminal functionality the radical of a compound that includes an aryl group having at least one directly bonded OGp substituent.

    摘要: Poly(propylene carbonates) are prepared from propylene oxide and CO2 with less than 10% cyclic propylene carbonate by product using cobalt based catalysts of structure preferably in combination with salt cocatalyst, very preferably cocatalyst where the cation is PPN+ and the anion is Cl− or OBzF5−. Novel products include poly(propylene carbonates) having a stereoregularity greater than 90% and/or a regioregularity of greater than 90%.
