Abstract
ία μέθοδος δια τον ειδικόν έν των χώρω πολυμερισμόν βινυλικών αιθέρων εχόντων τον γενικόν τυπον (Ι) είς τον οποίον το R είναι μία αλκυλική ρίζα περιέχουσα έως 5 άτομα άνθρακος, είς την μέθοδον δέ ταύτην ο πολυμερισμός, διεξέγεται παρουσία κατιοντικών καταλυτών αποτελουμένων εξ ενός στερεού διαλύματος ενο τριχλωριδίου ενο μεταβατικού μετάλλου των ομάδων IV ή V του περιοδικού πίνακος κατά τον Mendeleef μετά τριχλωριούχου αργιλίου.
A process for the specific polymerization of vinyl ethers having the general formula (I) in which R is an alkyl radical containing up to 5 carbon atoms, in which the polymerization process is carried out in the presence of a cationic catalyst consisting of a solute consisting of a solid a transition metal trichloride of groups IV or V of the Mendeleef periodic table after aluminum trichloride.
