ABSTRACT

We have synthesized styrene-acrylic latex and investigated the effect of such reaction conditions as the dosage of initiator, surfactant and stirring speed on monomer conversion and glass transition temperature (Tg) of polymer by means of orthogonal experiment, then we get the best reaction conditions. Test results prove that the glass transition temperature of the polymer is directly related to the monomer con- version. The improvement of monomer conver- sion can make the glass transition temperature close to the theoretical value. In the case of high final conversion, we can predict the glass transition temperature of the polymers of different composition according to the theoretical relation effectively.
