Wang, Hong; Lu, Jiantao; Feng, Pinzhen published the artcile< Synthesis and free radical polymerization of new spirocyclic monomer>, Reference of 112-63-0, the main research area is spirocyclic pentadecane derivative monomer preparation polymerization; radical polymerization spirocyclic pentadecane derivative monomer; ring opening polymerization spirocyclic pentadecane derivative.
A new type of monomer, 2-methylene-1,4-dioxo-dispiro[4.2.5.2]pentadecane was prepared through a series of organic reactions from simple com. materials. This spirocyclic monomer could undergo free radical ring-opening polymerization at 120° with dibenzoyl peroxide as initiator. The driving force for ring-opening was the relief of the strain at the central spiro atom as well as the formation of stable carbonyl group. However, it copolymerized with MMA (Me methacrylate) at the same condition without any ring opening. The structures of the monomer, resulting polymer and copolymer were determined by IR, NMR and MS. Mol. weight and its distribution of the polymers were estimated by GPC.
