実験手順

Operating with a reactor modified with respect to that used for the synthesis of POL 1, 2, 3 and 4, an isobutylene-1,3,5-hexatriene copolymer of low molecular weight was synthesised. 60 cm3 of methycyclohexane, 20 cm3 of methylene chloride, 28.4 g of isobutylene and 0.9 g of 1,3,5-hexatriene were fed, and the reaction was carried out at -10° C. 0.8 moles of AlEtCl2 were then introduced, and the mixture polymerised for fifteen minutes. 8.8 g of copolymer were isolated having a molecular weight of 10,000 and a conjugated unsaturation content of 0.38 moles/kg. By reaction with maleic anhydride, a functionalised polymer was obtained with 0.38 moles/kg of anhydride groups.
