DOI: 10.1080/01932691.2019.1571925

Abstract: Abstract Multi-armed polycarboxylate superplasticizers (SPCEs) were prepared via esterification-copolymerization in aqueous media from various polyols (including glycerol, xylitol and mannitol), acrylic acid (AA) and isopentenyl oxy polyethylene glycol ether (TPEG). The structures of the SPCEs… read more here.

DOI: 10.1166/mex.2019.1548

Abstract: In this paper, a facile method was adopted to synthesize polycarboxylate (PC) superplasticizers which rendered excellent initial fluidity and workability of mortar in 1 hour. Micro-crosslinking was introduced in the PC molecules and the ester… read more here.

DOI: 10.3390/molecules28020513

Abstract: In this work, a novel AaBAb-type triblock polycarboxylate superplasticizers (PCEs) with well defined molecular structures were designed and synthesized, firstly, by reversible addition-fragmentation chain transfer (RAFT) polymerization, to explore the structure–property relationship PCEs in the… read more here.
