Poly(methacrylates) with different kinds of dendritic moieties as side groups

Abstract

Abstract Alkyl methacrylate monomers with three kinds of dendritic fragments as alkyl groups, two kinds of Fréchet‐type and a new type with 3,5‐diphenoxybenzyl as first generation, were prepared by reaction of the corresponding dendritic bromides with methacrylic acid in good yield and were homopolymerized with a radical initiator. Polymers with side groups in first generation had a degree of polymerization ( P̄ n ) of 17–24, markedly higher than those with side groups in second generation, P̄ n ≈ 6–7.
