October 31, 2018 - Global Polycarboxylate Ether (PCE) Market is segmented into product and
geography. PCEs are composed by a methoxy-polyethylene glycol copolymer (side chain) grafted
with methacrylic acid copolymer (main chain). The carboxylate group -COO−Na+ dissociates in
water, provided a negative charge along the PCE backbone. The polyethylene oxide (PEO or MPEG)
group affords a non-uniform allotment of electron cloud, which gives chemical polarity to the side
chains.
The number and the length of side chains are flexible parameters that are easy to change. When the
side chains have a huge amount of EO units, they lower with their high molar mass the charge
density of the polymer, which enables poor performances on cement suspensions. To have both the
parameters on the same time, long side chain, and high indict density; one can keep the number of
main-chain-units much advanced than the number of side-chain-units.
