^[a]The series of polymers having alkyl groups were denoted by C_n-molecular weight averaged over the series, in which n is the number of carbons in the alkyl side chains.

^[b]f_HB=mole fraction of monomers with hydrophobic groups in a polymer chain.

^[c]DP=degree of polymerization (number of monomers in a polymer chain).

^[d]The number-average molecular weight of polymers (M_n) was calculated from f_HB, DP, and the molecular weights of monomers and methyl 3-mercaptopropionate.

^[e]Data reported previously.[40]
