Application

3,9-Divinyl-2,4,8,10-tetraoxaspiro[5.5]undecane is an acetal-type crosslinking agent comonomer and has been used:
  • in radical emulsion copolymerization of 2-hydroxyethyl methacrylate
  • as cross-linking agent in the synthesis of acid-degradable core-crosslinked micelles
  • in the synthesis of new biocompatible copolymer for loading the indomethacin as drug model
