Tert-butyl- and adamantyl-substituted alkene-bridged calix[4]arene monomers were synthesized by ring-closing metathesis (RCM). All the three possible conformers (cone, partial cone, and 1,3-alternate) were used as comonomers with cyclooctene and norbornene in ring-opening metathesis polymn. (ROMP). The resultant polymers were high-mol.-wt., transparent and stretchable materials with high calixarene incorporation (up to 25 mol% or 70 wt%) and low glass transition temps. [on SciFinder(R)]
