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.
Highlights
Styrene-acrylic latex is made of styrene and acrylate monomers, which has many advantages
Due to the minimum filmforming temperature has a good corresponding relation with the glass-transition temperature [6], so this paper mainly investigates the glass-transition temperature by means of optimizing the latex’s polymerization conditions
During the experiment we found that there is a big difference between measured value and theoretical value of Tg
Summary
Styrene-acrylic latex is made of styrene and acrylate monomers, which has many advantages It has wide source of raw materials, high function/price ratio, simple synthetic process and the latex has outstanding water resistance, alkali resistance, scrub resistance and the paint film has good outdoor durable, adhesive attraction. In order to adapt to different environment, especially the temperature environment, it requires the minimum film-forming temperature can has an unchangeable temperature. Scholars in this area had focused mostly on performance optimization but ignored the investigation of minimum filmforming temperature. We obtain latex with high conversion, we can solve the above problems in polymerization technology aspect and obtain the latex recipe of different glass transition temperature under the guidance of the theoretical relation
