Synthesis and characterization of linear dendritic homo and copolymers acrylated behera amine

A co-polymerizable dendron of first generation synthesized from behera amine was homopolymerized and copolymerized with commercial monomers such as styrene, methyl methacrylate, and N-vinyl pyrrolidone. Characterization of the co-polymers was performed and it was found with the help of FT-IR and proton and carbon NMR that copolymerizable dendron, ACTES (ACrylated TriESter, first-generation dendron of acrylated behera amine) was incorporated in the co-polymer chains. Besides, the reactivity ratio pairs of the ACTES monomer with both styrene and n-vinyl pyrrolidone were determined. The reactivity ratio pair for ACTES and MMA could not be determined by neither gravimetrically nor with NMR. After experiments and calculations, the reactivity ratio pair for styrene and ACTES was found to be rst = 0.27 and rac = 0.44 and for NVP and ACTES rnvp = 0.36 and rac = 1.01. By utilization of the reactivity ratio of ACTES, “Q” and “e” values were determined in order to be able to draw some conclusions about the reactivity behavior during copolymerizations. “Q” = 1.152 and “e” = 0.66 were found with respect to styrene as reference. These values indicates the steric effect of ACTES was more dominant in copolymerizations.
