A　polycarboxylate　superplasticizer　(PCE)　was　synthesized　in　a　non-solvent　system　with　bulk　polymerization　and　then　was　pulverized　into　powdered　form　to　achieve　a　rapid　transportation　and　convenient　preparation.　PCE　synthesized　by　using　isopentenyl　polyethylene　glycol　(TPEG)　or　isobutenyl　polyethylene　glycol　(IPEG)　as　a　macromonomer　exhibited　the　best　fluidities　and　retaining　properties　at　80　degrees　C　and　75　degrees　C,　respectively.　Besides,　azobisisobutyronitrile　(AIBN)　was　suitable　as　an　initiator,　and　the　fumaric　acid　was　suitable　as　the　third　monomer.　The　test　results　of　H-1　nuclear　magnetic　resonance　(H-1　NMR)　confirmed　the　occurrences　of　polymerization,　and　the　measurement　results　of　molecular　weight　and　distribution　showed　that　PCE　molecular　weight　characteristics　were　in　accordance　with　their　fluidity　properties　in　cement　paste.　The　application　performances　in　cement　showed　that　PCEs　with　the　best　paste　fluidity　retentions　had　the　longest　final　setting　time　and　the　shortest　setting　time　interval,　and　the　PCEs　with　good　fluidity　properties　can　obviously　delay　the　hydration　process　and　lower　the　hydration　heat.　Accordingly,　this　is　a　novel,　energy-saving　and　economical　method　to　prepare　powdered　PCE　in　the　field　of　concrete　admixtures.
