Abstract
We present an approximation simulation study on the dynamics of a comb polymer chain, such as –(–A–BR–)–x, with and without excluded volume, where R is the side chain. The dynamics of comb polymer chains are studied by investigating the dynamics of the equifinal linear polymer chains, –(–A–B′–)–x, with the probability of movement of B′ bead p. It is found that relaxation times of the first three normal modes obey the relation Tk(P)—(N – 1)1.96/k1.97p0.70 in the absence of excluded volume, and Tk(P)—TklPβκ(β1=0.5, β2=0.75, β3=0.72) in the presence of excluded volume, where N=2x and Tkl is the relaxation time of the first three normal modes Tk of linear polymer chains (k=1, 2, and 3).
