    Description / Table of Contents: Poly(N-vinylpyrrolidon-co-vinylamin) und Poly(N-vinylpyrrolidon-co-glycidylcrotonatSystematic name: (2,3-Epoxypropyl)crotonate.) wurden mittels Atherton-Todd- und Fields-Kabachnik-Reaktion sowie durch direkte Umsetzung mit Phosphortrichlorid oder Phosphortrichloridoxid phosphoryliert. Zusammensetzung und Struktur der Endprodukte wurden durch 1 H-NMR-, 31 P-NMR- und IR-Spektroskopie sowie elementaranalytisch bestimmt.
    Notes: Phosphorylation of poly(N-vinyl pyrrolidone-co-vinyl amine) and poly(N-vinyl pyrrolidone-co-glycidylcrotonateSystematic name: (2,3-Epoxypropyl)crotonate.) is realized by Atherton-Todd and Fields-Kabachnik reactions and by the means of direct interaction with phosphorus trichloride and phosphorus trichloride oxide. The composition and structure of the isolated final products was proved by NMR (1H and 31P), IR spectroscopy and elemental analysis.

    Description / Table of Contents: Poly(N-vinylpyrrolidon-co-vinylamin) wurde mit Estern verschiedener Phosphorsäuren (Dimethylphosphit, Methanphosphonsäuredimethylester, Trimethylphosphat und Bis-(2-chlorethyl)-phosphonat methyliert, um physiologisch aktive Polymere zu erhalten. Die alkylierten Produkte wurden mittels IR- und NMR-Spektroskopie sowie Elementaranalyse charakterisiert. Der Alkylierungsumsatz hängt vom verwendeten Alkylierungsmittel ab. Die methylierten phosphorhaltigen Polymeren weisen Herbizidaktivität auf und könnten als Pflanzenwachstumshemmer verwendet werden.
    Notes: Alkylation of amino groups bounded to a polymer chain with esters of phosphorous acids was studied in order to obtain physiologically active polymers. Poly(N-vinyl-pyrrolidone-co-vinylamine) was chosen as a polymer-carrier. The phosphorous acid esters used were dimethyl hydrogen phosphonate, dimethyl methanephosphonate, trimethyl phosphate and bis-(2-chloroethyl)-hydrogen phosphonate. The composition and structure of the isolated final products was proved by IR- and NMR-spectroscopy and elemental analysis. It is established that alkylation takes place to various extents.The obtained alkylated phosphorous-containing polymers exhibit herbicidal activity and could find application as plant growth retardants.
