Abstract

<p>Furan terminated vegetable oil derivatives were obtained by the reaction with 4-(furan-2-ylmethoxy)-4-oxobutanoic acid. Diels－Alder polymerizations of furan terminated vegetable oil derivatives and bismaleimides were carried out at 75 ℃ to give new transparent network polymers. The structures of the network polymers were confirmed from FTIR and 13C CPMAS. The network polymer synthesized from castor oil derivatives (FMECO) and bis (3-ethyl-5 methyl4-maleimidophenyl) methane (M1) exhibited high tensile strength (48.3 MPa) and good adhesion to stainless steel plates. It was found that these network polymers showed greater shear adhesive strength than initial one after repeated depolymerization－re-crosslinking process by heating.</p>
