\usepackage{chemfig}
\usepackage{chemmacros}
    \chemsetup{
        modules = all,
    }
\begin{document}
\begin{figure}[H]
\centering
\definesubmol{pvc}{CH_2-CH(-[:90]Cl)}
\chemfig{-!{pvc}- \color{green}{!{pvc}} -!{pvc}-}
\end{figure}
\end{document}

根据以下帖子回答这里

\documentclass[12pt]{article}
\usepackage{float}
\usepackage{chemfig}
\usepackage{chemmacros}
\chemsetup{
    modules = all,
}

    \begin{document}
    \def\GREEN{\gdef\printatom##1{\color{green}\ensuremath{\mathrm{##1}}}}
    \def\BLACK{\gdef\printatom##1{\color{black}\ensuremath{\mathrm{##1}}}}
    \begin{figure}[H]
        \centering
        \definesubmol{pvc}{CH_2-CH(-[:90]Cl)}
        \chemfig{-!{pvc}(-[,,,,draw=none]\GREEN)([,,,,green]-!{pvc}-)\BLACK!{pvc}-}
    \end{figure}
\end{document}
