Abstract: Oligomers (I) of open-chain N-vinylcarboxamides of formula CH2=CH-N(R')-C(O)-R (II) and optionally comonomer(s), prepared by cationic polymerisation using a finely-divided inorganic solid (III) with a tertiary halide of formula (R )(R )(R )C-X (IV) adsorbed on its surface, are new; in which R, R' = hydrogen (H) or 1-6 carbon (C) alkyl; R , R , R = 1-15 C alkyl, aryl or methoxyphenyl; X = halogen.
