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
