Cover: Polyisoprenes were found to form inclusion complexes with cyclodextrins with high selectivity to give crystalline compounds. β-Cyclodextrin formed complexes only with polyisoprene of low molecular weight. γ-Cyclodextrin formed complexes with polyisoprenes of high molecular weight. α-Cyclodextrin did not form complexes with polyisoprene of any molecular weight.
