| Abstract: | Radical polymerizations of methyl methacrylate (MMA) using graphene or lignin-derived graphene as additives give the corresponding poly(MMA)s of which much wider molecular weight distribution (MWD) than that of the poly(MMA) without additives. The MWD of the resulting poly(MMA) using graphene is wider compared to that using lignin-derived graphene, suggesting that the structural differences between the two graphene compounds affect radical polymerization behavior. Furthermore, the radical polymerizations of methacrylate monomers with different substituents using the two graphene compounds are performed, leading to the additive effect of the two graphene compounds which is relevant to the steric hindrance of the monomer. |
