    Notes: Photoinitiated polymerization of 4-methylene-2-phenyl-1,3-dioxolane (1) was carried out using either tris (4-methylphenyl) sulfonium hexafluoroantimonate or 4-decyloxyphenyl phenyliodonium hexafluoroantimonate as initiators. 1H-NMR analyses confirmed exclusive ring-opening while DSC and SEC were used to determine the glass transition temperatures (Tgs) and molecular weights, respectively. Photoinitiated cationic copolymerizations of 1 were investigated with several acyclic and cyclic monomers. Copolymerization of 1 with vinyl ethers and a spiroorthoester resulted in copolymers whose thermal properties were dependent on comonomer ratios. Copolymers of 1 and dihydrofuran or dihydropyran afforded soluble polymers with Tgs significantly higher than the homopolymer of 1. © 1997 John Wiley & Sons, Inc.

    Notes: Poly[styrene-co-(diethyl vinylbenzylphosphonate)] and poly[methylmethacrylate-co-(diethyl vinylbenzylphosphonate)] were prepared and used in modified Horner-Emmons reactions to synthesize polymers with covalently attached stilbene groups. This versatile new method allowed for the preparation of polymers with either electron-donor (OCH3, CH3) or electron acceptor (Br, NO2) substituents on the stilbene aromatic ring. The resulting polymers were characterized by 1H NMR, FT-IR, UV-visible, DSC, and size exclusion chromatography. Efficient transformation of polymeric phosphonates to the polymeric stilbene derivatives was realized. Size exclusion chromatographic analyses demonstrated that the reaction conditions have no deleterious effect on the molecular weight distribution of the various polymers that were prepared. Photochromic behavior was demonstrated for one of the derivatives. © 1995 John Wiley & Sons, Inc.
