of this functional group in PS-DVB polymers with different loading and cross-linking degrees, as well as on SMOP resins. These functionalized resins have been used to prepare Ti-TADDOL-supported complexes which have been tested as catalysts in the reaction of cyclopentadiene with 3-crotonoyl-1,3-oxazolidin-2-one. Although all the polymers obtained efficiently catalyze the reaction, only the one prepared
