## Abstract Summary: The __oligomeric__ A~2~ plus monomeric B~3~ synthetic methodology provided highly branched, poly(ether urethane)s based on TMP (B~3~) and isocyanate endcapped polyethers. ^13^C NMR spectroscopic assignments for the branched polyurethanes were verified using model urethane‐conta
