In a significant development, complex 3 was found to catalyze insertion copolymerization of industrially relevant 1,1-disubstituted difunctional vinyl monomers for the first time. Thus, insertion copolymerization of ethyl-2-cyanoacrylate (ECA or super glue) and trifluoromethyl acrylic acid (TFMAA) with ethylene produced the corresponding copolymers with 6.5% ECA and 3% TFMAA incorporation. Increasing the concentration of difunctional olefins led to higher incorporation but at the expense of lower activities. These observations indicate that complex 3 tolerates difunctional vinyl monomers and provides direct access to difunctional polyolefins that have not been attempted before.</p>1 aGaikwad, Shahaji, R.1 aDeshmukh, Satej, S.1 aGonnade, Rajesh, G.1 aRajamohanan, P., R.1 aChikkali, Samir, H.  uhttps://library.ncl.res.in/content/insertion-copolymerization-difunctional-polar-vinyl-monomers-ethylene-1
