## Poly(vinylamine) , PVA, complexes with cobalt chloride hexahydrate exhibit a 45 Β°C enhancement in the glass-transition temperature per mol % of the d-block metal cation. Poly(ethylene imine), PEI, complexes with CoCl 2 (H 2 O) 6 exhibit a 20 Β°C enhancement in T g per mol % Co 2Ο© . Since the bas
Very high molecular weight poly(vinylamine) was prepared by a modified Hofmann rearrangement of poly(acrylamide). The reaction was carried out in ethylene glycol using the monosodium salt of this solvent and bromine instead of sodium hypohalogenides in the original Hofmann rearrangement. Poly(vinyl
## Abstract The optical properties of poly(vinylamine) containing optically active (+)β or (β)β2β(thyminβ1βyl) propionyl groups as grafted pendants (PT) and the related monomer (MT) and dimer models (DT) were investigated by UV, circular dichroism (CD), and NMR spectroscopy. Highly syndiotactic PT
