Synthesis and Dispersion Properties of Lower Salt Resistance Sulfomethylated Phenol Formaldehyde Resin (LSMP)

Abstract:

A lower salt resistance sulfomethylated phenol formaldehyde resin (LSMP) was synthesized. The dispersion properties of LSMP and influences of reaction conditions on its properties were investigated with dynamic light scattering technology, and means of viscosity and critical coagulating concentration (CCC) determination. The result shows that the viscosity of a 1.0 g•L-1 resin solution ranges from 0.8036 mPaּs to 0.8705 mPaּs, and unit in distilled water exhibits a hydrodynamic diameter between 8.5 nm and 123.4 nm and a Zeta potential varying from -76.05 to -21.12 mV under different reaction conditions. The dispersing system of LSMP in water is a kind of colloid solution and electrolytes can weaken the resin dispersion and make the resin flocculate, and the solution of LSMP in water is hypersensitive to positive ions and effects of positive ions will be more obvious with increasing valence of ions.
