durch Umsetzung des entsprechenden allein durch R2 und R' substituierten Phenylpropylhalogenids mit einem Alkohol, Alkylhalogenid der Olefin und Phenylpropylhalogenide, in denen R3 bestimmte Bedeutungen hat.
Catalyst composition solid at room temperature, based on alkali metal lactamate, characterized in that the content of methanol, ethanol and η-propanol is lower than 0,2 wt.% and that 0.1-5 wt.% of another alcohol is present, chosen from isopropanol or a branched or unbranched aliphatic or aromatic alcohol with 4-18 carbon atoms, which alcohol has a boiling point of 80◊C to 250◊C.
This catalyst composition is suitable for lactam polymerization, especially in RIM techniques.
Nylon block copolymer prepared with said catalyst composition and articles made from this nylon block copolymer.
The present invention provides a process for making hydrocarbyloxymagnesium halides by reacting in an inert atmosphere under anhydrous conditions activated magnesium metal with an oxygen containing compound of 1 to 20 carbon atoms and an anhydrous hydrogen halide to produce a hydrocarbyloxymagnesium halide.
This invention relates to a detergent composition which contains a surfactant, a builder, water and a solvent mixture. The solvent mixture comprises hexylene glycol and an aliphatic monohydric alcohol containing at least 6 carbon atoms. The alcohol may be a monoether of a mono-, di- or polyoxyalkylene glycol. The compositions are particularly suitable for cleaning hard surfaces e.g. baths.
