Abstract
Poly(disulfido-imide)s were prepared by Diels-Alder (DA) reaction of furfuryl-disulfide (FDS) with the various bismaleimides. The DA reaction was carried out in xylene as solvent, as well as in bulk, followed by aromatization of tetrahydropthalimide intermediates in the presence of acetic anhydride. All the poly(disulfido-imide)s (PDSI)s were characterized by elemental analyses, IR spectral data, and thermogravimetry. The poly(disulfido-imide)s (PDSI)s exhibit moderate thermal stability. Preliminary test for glass reinforcement of the poly(disulfido-imide) (PDSI) indicates that laminates with good mechanical strength can be obtained.
