Novel interacting blends based on acryl terminited oligoimides and vinyl monomers


New amino terminated oligoimides (AOIs) were prepared by the Michael addition reaction of bismaleimide (1), namely [1, 1’-{1, 4-phenylenebis (methylene)}bis(1H-pyrrole-2,5-dione)] with excess of various diamines(2a-c). These AOIs were characterized by elemental analysis, FT-IR spectral studies, number average molecular weight estimated by non-aqueous conductometric titration and by thermogravimetry. AOIs were then treated with acrylol chloride and resultant acryl terminated oligoimides (AcOIs) samples were characterized thermogravimetrically. Each of these AcOI was then combined with the N-phenyl maleimide(PM) in THF solvent. The resultant suspensions were then heated in the presence of azobisisobutyronitrile (AIBN) as an initiator. The AcOI and PM may homo polymerized through double bond or may crosslinked simultaneously. Thus this form interacting blends, which were analyzed thermogravimetrically. The glass fiber reinforced composites were fabricated by using the suspensions of the AcOI and PM. The composites of interacting blends were analyzed for their mechanical, chemical and electrical properties.
