    Notes: Carbamoyl phosphonate derivatives of methacrylic acid and α-methyl styrene were synthesized in good yield by reacting dimethyl and diethylphosphite with isocyanato ethylmethacrylate (IEM) or with meta-isopropenyl-α,α-dimethylbenzylisocyanate (m-TMI). The IEM derivatives yield soluble homopolymers with common radical initiators. The m-TMI carbamoyl phosphonates were copolymerized with styrene and with acrylates yielding soluble materials with better than 50 mol % incorporation of the phosphonate monomer. The side chain carbamoyl phosphonate group drastically lowers the Tg relative to those of the parent polymers. Thermogravimetric studies suggest the NHC(O)—P(O)(OR)2 bond to be stable to about 225°C. The radiopacifying salt UO2(NO3)26 H2O yields transparent films with the phosphonate-containing polymers. The Tg increases with uranyl content. © 1993 John Wiley & Sons, Inc.

    Notes: In solvents of low polarity, salts containing a carbanion, e.g. fluorenylsodium, or a radical anion, e.g. coronenesodium, can exist as contact ion pairs or as solvent separated ion pairs. Particular interest attaches to the complexes of ion pairs with the strongly solvating, polydentate polyglycol dimethyl ethers (glymes) and with crown compounds. These systems can be studied by optical spectroscopy, NMR spectroscopy, and other methods.
