Abstract:
(-)-Galanthamine (I) or (Ia) is obtained in substantially high yield and purity substantially without concomitant production of epigalanthamine by conversion of racemic narwedine to (-)-narwedine (II) or (IIa) and subsequent reduction to (-)-galanthamine using bulky organo-aluminum or organo-boron reducing agents.
Abstract:
The claims encompass hard surface cleaner and hard surface treatment compositions containing particular ampholytic polymers which impart not only good residua! cleaning properties but in particular give fast drying properties to the cleaning compositions. The polymers are for example terpolymers formed from diallydialkyammonium chloride, anionic monomers and N,N Cdi-C1-C8 alkyl (meth)acrylamides.

Abstract:
Novel ampholytic ter-polymers comprising at least an ethylenically unsaturated cationic monomer, a monomer containing a carboxylic acid or sulfonic acid group and diallyamine or derivative are claimed. Further, the ter-polymers may be used in personal care or personal washing compositions optionally in the presence of conditioning agents such as silicone, fatty amines, fatty amine oxides and fatty quaternaries and/or various benefit agents. The ter-polymer compositions are especially useful in the treatment of keratin-containing substrates. Keratin substrates include, but are not limited to, animal and human hair, skin and nails.
Abstract:
Electrically active, cathodically coloring electrochromic polymers are blended with a non-electrochromic, non-electrically conductive binder polymer to provide an electrochomic composition with greatly enhanced performance in an electrochromic device over time. It is also found that blending an electrochromic polymer with a non-coloring electroactive material allows for greater design in preparing electrochromic devices as it enables the use of a higher amount of typically low coloring anodic materials due to increased need for charge balancing.
