Abstract

Polychloroprenes CR containing pendant cyclopentadiene Cp functions have been synthesized by treating the rubbers with dimethylcyclopentadienyl-aluminum Me2 CpAl. Optimum reaction conditions have been determined. Cyclopentadienylated polychloroprenes CR-Cp gelled on drying, however, the products became soluble upon treatment with strong dienophiles, e.g., maleic anhydride or dimethyl acetylenedicarboxylate. Evidently gelation is due to Diels-Alder addition of pendant Cp groups and may lead to thermally reversible networks.
