The pyrolysis of N‐(α‐methoxyethyl) acetamide, which was obtained by one‐step reaction of acetamide, acetaldehyde, and methanol, gave N‐vinylacetamide (NVA) in a good yield. The polymerizability and copolymerizability of NVA were studied. Free radical polymerization was carried out in the presence of radical initiator or by γ‐ray irradiation. The monomer reactivity ratios of NVA were estimated in the copolymerization with acrylamide, vinyl acetate, and methyl methacrylate. The solvents were found to influence the monomer reactivity ratio. NVA showed a typical copolymerizability as nonconjugated vinyl monomer, and Q and e values were obtained in DMF as 0.16 and −1.57, respectively.

The esterification of a carboxy group terminated vinylpyrrolidone oligomer with chloromethylstyrene under mild conditions resulted in a styryl terminated oligovinylpyrrolidone macromonomer. The purity of the obtained macromonomer was greater than 95%. Copolymerization of the macromonomer with styrene in ethanol using BPO as catalyst yielded a graft copolymer having a hydrophobic backbone and amphiphilic branches, which was found to have a spherical form and was dispersable in water and ethanol. ZUSAMMENFASSUNG:Die Veresterung eines carboxygruppenterminierten Vinylpyrrolidon-Oligomeren mit Chlormethylstyrol unter milden Bedingungen filhrte zu einem styrylterminierten Oligovinylpyrrolidon-Makromonomeren. Die Reinheit des erhaltenen Makromonomeren war grUBer als 95%. Die Copolymerisation des Makromonomeren mit Styrol in Ethanol mit BPO als Katalysator ergab ein Pfropfcopolymeres mit hydrophobem Rilckgrat und amphiphilen Seitenketten, das eine kugelformige Gestalt hatte und dispergierbar in Wasser und Ethanol war.

Chiral bis(1,10-phenanthroline) with Tröger’s base skeleton (1) was synthesized from 5-amino-1,10-phenanthroline with formaldehyde and HCl. Racemic 1 could interact with DNA from CD spectroscopy and could cleave DNA when it was complexed with copper(I).
