With　the　rapid　development　of　the　construction　industry,　it　is　necessary　to　synthesize　environment-friendly　functional　polymers,　especially　when　developing　＂green＂　construction　industry　types.　Herein　a　novel　solid-state　polycarboxylate　superplasticizer　(PCE)　with　low　energy-consumption　was　designed　and　synthesized.　In　industrial　application,　solid-state　PCE　has　exhibited　better　cement　paste　fluidity　and　concrete　slump　compared　to　liquid-state　PCE.　A　life　cycle　assessment　(LCA)　of　the　PCE　synthesis,　the　packaging　materials　used,　and　the　transportation　of　the　PCE　were　conducted　based　on　the　ReCiPe　method.　The　results　indicated　that　liquid-state　PCE　has　a　far　greater　environmental　impact　at　＞60%　than　solid-state　PCE,　which　is　less　significant　at　＜40%.　The　inventory　data　that　are　associated　with　the　production　of　the　new　polymer　are　disclosed　for　the　first　time　to　enrich　the　related　database　in　this　field.　This　study　demonstrates　the　optimization　of　the　state　and　synthesis　technique　of　a　functional　polymer,　improving　the　performance　and　lowering　the　environmental　impacts　involved　in　producing　the　polymer,　while　reducing　the　risks　to　human　health　and　protecting　the　ecosystem　at　the　same　time.
