New Copolymers of Vinylphosphonic Acid with Hydrophilic Monomers and Their Eu Complexes.

Free radical copolymerization is used for the synthesis of novel water-soluble copolymers of vinylphosphonic acid with 2-deoxy-2-methacrylamido-D-glucose or 4-acryloylmorpholine, with varied compositions and molecular masses, as well as for the synthesis of copolymers of vinylphosphonic acid with acrylamide. The obtained copolymers contain 6-97 mol.% of vinylphosphonic acid units, and their molecular masses vary from 5 × 10 to 310 × 10.

Interpolymer Complexes of Poly(methacryloyloxyethyl phosphorylcholine) and Polyacids.

It has been shown that macromolecules of poly(methacryloyloxyethyl phosphorylcholine) can form hydrogen bonded interpolymer complexes with homo- and copolymers of carboxylic acids and with poly(vinylphosphonic) acid in aqueous solutions. Polarized luminescence and IR spectroscopy were applied in the investigation. Nanosecond relaxation times characterizing the mobility of the chain fragments for the initial luminescent labeled polymers were determined and their changes by a factor of 2-50 were established during the formation of an interpolymer complex.

Crystal structure of a Co coordination polymer: -poly[[μ-aqua-bis-(μ-2-methyl-propano-ato)-κ:';κ:-cobalt(II)] monohydrate].

In the title cobalt(II) coordination polymer with isobutyrate ligands, {[Co{CH(CH)CO}(HO)]·HO} , the Co ion is hexa-coordinated in a slightly distorted octa-hedral coordination environment defined by two O atoms from two bridging water mol-ecules and four O atoms from four bridging carboxyl-ate ligands. The carboxyl-ates adopt two different coordination modes, μ-(κ:') and μ-(κ:), forming a one-dimensional polymeric chain extending along [010]. The intra-chain cobalt⋯cobalt separation is 3.
