Polyethers containing 1,3-butadiene skeletons in the backbone were prepared from the polycondensation of 2,3-diiodemethyl-1,3-butadiene (2b) and bisphenols (3). Although the polymerization conditions were limited due to the low reactivity of 2b, a series of polyethers was obtained under the optimized conditions. These polymers exhibited glass transition temperatures (T(g)s) around 130 degrees C, while curing points (T(cure)s) were observed around 245 degrees C. In addition, P2b/3a afforded a network polymer by the copolymerization with styrene.
