Zur kationischen Polymerisation von reaktiven Monomeren in Gegenwart nucleophiler Gegenionen

Abstract: Die kationische Polymerisation von Isobutylvinylether und p-Methoxystyren wurde niit Triphenylmethylverbindungen initiiert, die nucleophile Gegenionen, wie Chlorid, Bromid, Nitrat oder Sulfat, enthalten. Als Losungsmittel wurden Nitromethan, 1,2-Dichlorethan und Metliylenchlorid im Gemisch mit SO, eingesetzt. Bei allen Polymerisationen wurden Protonenubertragungen auf die nucleophilen Gegcnionen beobachtet. Die Protnncnubertragung wurde an Modellreaktionen mit 1,l-Diphenylmethyl-nieth-l-ylium uiid nucleophilen… Show more

“…m-cresol 16 and liquid sulfur dioxide. 17 For nitroalkanes and solvent mixtures, see ref 18. Unfortunately, in these cases the monomer consumption is not complete, the MWD is very broad, and the structure of the polymer is not uniform due to isomerization and side reactions.…”

“…Unfortunately, in these cases the monomer consumption is not complete, the MWD is very broad, and the structure of the polymer is not uniform due to isomerization and side reactions. [16][17][18] The initiation of vinyl ether polymerization in solution by completely ionized carbenium salts is by now a well-established method. 19,20 In 1991 we reported for the first time on the cationic polymerization of p-methoxystyrene as a model monomer using trityl halides (fluoride, chloride, and bromide) on the surface of Aerosil particles as initiator systems in 1,2-dichloroethane suspension at room temperature.…”
