ABSTRACT:
Novel thermosetting resin compositions are disclosed which comprise a 2,7-dioxo-1,6-dioxaspiro[4.4]nona-3,8-diene compound and at least one other reactive, polymerizable monomer which has at least two functional group substituents which contain active hydrogen atoms or multiple bonds between adjacent atoms. The thermosetting resins, upon application of heat, give crosslinked, cured products having good properties.
