1) SMAS can be used in Polycarboxylate Superplasticizer(PC) as the
chain transfer agent .Keep the PC being off odour ,meanwhile
indraughting sulfonic acid group with high dispersion and
dispersion retention ability. Good effect for plasticizer of cement
2) As a monomer of corrosion and scale inhibitors, this product can
be used in water treatment chemicals. It can polymerize with
acrylic acid, acrylamide, maleic anhydride, sodium hypophosphite
and has good scale inhibition effects for calcium phosphate, zinc
salts, carbonate calcium and calcium sulfate.
3) As an oil field chemical, it can polymerize with acrylamide,
acrylic acid, sodium humate, acrylamido propyl trimethyl ammonium
chloride, acrylamido-ethyl-2-methyl ammonium chloride, diethyl
diallyl ammonium chloride, allyl trimethyl ammonium chloride to be
dispersants, fluid loss agent and have remarkable effect in
anti-high temperature and salt.
4)As the third monomer of acrylic fiber, this product can improve
the dyeing properties, the heat resistance and flexibility of
fibers, so they can absorb color fast and have strong fastness and
5) As a paint additive, it can be used to produce thermosetting
acrylic resin and coating dispersant to increase the
6) As a monomer of flocculant, it can polymerize with acrylamide.
7) It can polymerize with methyl acrylic acid, itaconic acid to be
8) It can be used to make CPPL and high water-absorbing resin in
electronics and materials processing.
9) It can polymerize with sodium acrylate, styrene-acrylic
emulsion, polyvinyl alcohol to improve fertilizer about red soil
and strengthen absorb ammonium ion, nitrateion.
10) It can be used for the third oil displacement agent.
11) As one dry strength agent of papermaking additives, it can
improve the quality of the paper.
