摘要
Di-tert-butyl maleate (DtBM) did not polymerize with 2,2'-azobis (isobutyronitrile) as a radical initiator, but DtBM easily homopolymerized via a monomer-isomerization radical polymerization mechanism to give a high molecular weight polymer when morpholine was added into the polymerization system as an isomerization catalyst. The feature of the monomer-isomerization polymerization-of DtBM was investigated in detail. The polymer obtained was confirmed to consist of a poly (tert-butoxycarbonylmethylene) structure similar to that from di-tert-butyl fumarate. Subsequent pyrolysis of the resulting polymer at 180-degrees-C is a useful route to synthesis of a high molecular weight poly(fumaric acid).
