Disclosed herein are a process and composition to make polymerizable resins containing oxazolidone, in which organic acid-catalyzed and/or thermal annealing process got involved and consequently promoted a unique intramolecular transformation from a linear urethane linkage to a cyclic urethane linkage for those specifically constructed urethane resins containing α-substituted β-ketone moieties.
