Development of lignin-based polycarboxylates as a plasticizer
Plasticizers, such as lignosulfonate (LS) or polycarboxylate ether (PCE), have been used to reduce the amount of added water in cement paste, which is advantageous because water reduces the strength of hardened cement (Plank et al. 2010; Huang et al. 2018).
Title: A Review on Plasticizers and Eco-Friendly Bioplasticizers
Bioplasticizers such as epoxidized plant oils, cardanol, citrates and Isorbide esters are derived from further modifications of oils and triglyceride, starch and cellulose, citric acids and...

- What is a polycarboxylate superplasticizer?
- Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study,...
- Is PCE 45pc2 a jellyfish-like superplasticizer?
- Surprisingly, the hydrodynamic radius of the comb-shaped PCE 45PC2 was similar to that of the jellyfish-like superplasticizer, in spite of its considerably higher molecular weight.
- Does a superplasticizer contain a hyperbranched polyglycerol scaffold?
- Therefore, this study aims to present the synthesis of a new type of superplasticizer, which contains a hyperbranched polyglycerol scaffold, and to evaluate the dispersing properties of such moieties in cement.
- What is a carboxymethylated hyperbranched polyglycerol?
- Moreover, a carboxymethylated hyperbranched polyglycerol was synthesized that does not comprise a linear EO/PO side chain. This polymer was denoted as TMP (hyp.PG) (COOH) n and prepared in a two-step synthesis from trimethylol propane (TMP) and glycidol (see Scheme 2).
- Which polymer has a higher molar mass than a jellyfish-like superplasticizer?
- Considering the molar masses of the polymers, it became apparent that TMP (hyp.PG) (COOH) n holds a higher proportion of the carboxymethylated hyperbranched polyglycerol skeleton than the jellyfish-like superplasticizer. The hydrodynamic radii of the synthesized polymers are presented in Table 2.
- What is the structure of a jellyfish-like superplasticizer?
- Structural Analysis of the Polymers The hyperbranched structure of the jellyfish-like superplasticizer was achieved by anionic ring opening polymerization of glycidol using a partially deprotonated bis-glycidolized Jeffamine as initiator.
