Abstract:

Poly(ESA-AA-SAS-HPA) was synthesized by solution polymerization from epoxy succinic acid (ESA), acrylic acid (AA), sodium allyl sulfonate (SAS) and hydroxypropyl acrylate (HPA). It was characterized by FT-IR,1H NMR, TG and DLS. The effects of chelating pH, temperature and additive mass fraction on the washing aid performance of Poly(ESA-AA-SAS-HPA) were investigated. The results show that, compared with sodium tripolyphosphate, it has good washing aid performance, with the chelating amount of 308.7 mg/g and the calcium dispersing power of 101.5 mg/g. Poly(ESA-AA-SAS-HPA) has good synergism with sodium dodecylbenzene sulfonate (LAS), which can reduce the surface tension of the system to 45 mN/m.

Key words: solution polymerization, washing aid, polycarboxylate
