The application of the “inifer technique” introduced by J.P. Kennedy et al. for the preparation of polyisobutylene (PIB) with two reactive end‐groups results in a new range of functionalized polymers. These products can be blended with polymers to improve the network structure. This presentation deals with the preparation of PIB‐telechelics, their characterization and their application in combination with polychloroprene. During the mixing step we observed an improved processibility of polychloroprene based on the plastifying efficiency of these telechelics. The vulcanization conditions are described under which vulcanization with improved technical properties can be achieved, in summary, the addition of 10–30 parts PIB improves the low temperature flexibility, the weathering and ageing resistance of the polychloroprene vulcanizates. The use of these blends in various fields of application is explained.
