Abstract

95 parts of isobutylene were copolymerized with 5 parts of isobutenyl cyclopentene prepared by dehydrochlorinating 2-chloro-isobutyl-cyclopentene.ALSO:The invention comprises compounds of the general formula <FORM:0881555/IV (b)/1> where R represents a haloalkyl radical containing 2 to 20 carbon atoms and where the halogen atom is attached to a secondary or tertiary carbon atom and where R1 and R11 represents hydrogen or a C1 to C3 alkyl group, the substituents R, R1 and R11 being carried on saturated carbon atoms, and a process for their preparation by reacting an olefin hydrocarbon with a halocyclopentene in the presence of a Friedel-Crafts catalyst. Examples describe the reaction of chlorocyclopentene with propene, butene and isobutene. 2-Hydroxy-isobutyl glutaric acid-g -lactone may be prepared by oxidising 2-chloro-isobutyl-cyclopentene with potassium permanganate. Alkenyl cyclopentenes may be prepared by dehydrohalogenating the cyclopentenyl haloalkanes.
