Abstract: The invention relates to a method for producing halogen-free, reactive polyisobutene with a terminal double-bond content of over 50 mol % and an average molecular weight of 2,800 - 10,000 Dalton by cationic polymerization of isobutene or isobutene-containing hydrocarbon mixtures in a liquid phase, wherein polmerization is carried out at a temperature of -30 ~C to +40 ~C in the presence of a heterogeneous polymerization catalyst from one or several oxides of the elements of the 5th and 6th subgroup of the periodic table of elements or in the presence of a heterogeneous polymerization catalyst containing one or more oxidic compounds of one or more elements of the 5th and 6th subgroup of the periodic table of elements on an oxygen-containing zircon compound of various non-zeolitic oxidic supporting material, wherein said catalyst contains no technically active quantities of halogen.

Abstract: Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R and R are alkyl or R and R and the common C atom are 5-membered to 7-membered cycloalkyl; R is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.
