The performance of devolatilization for cleaning industrial latexes was investigated. It was found that both steam and air saturated with water were very efficient in volatile organic compound (VOC) removal, as well as in controlling the solids conte

The main aspects of post-polymerization and devolatilization for cleaning industrial latexes were analyzed. Monomer partitioning was studied and we found that most of the monomer was portioned into the polymer particles, independently of its water so

A mathematical model able to predict monomer removal and new volatile organic compound (VOC) formation during postpolymerization was developed. The model was validated in the postpolymerization of vinyl acetate (VAc) containing latexes. Then, the mat

The effect of treating several commercially important emulsion polymers with different initiator systems was investigated. The initiator system producing highly reactive tert-butoxyl radicals was able to cause polymer modification. This represented a

The mechanisms involved in monomer removal by postpolymerization were investigated to establish a criterion to select the most effective initiator systems. Three redox systems yielding radicals of different hydrophobicities were studied. Efficiency i

The postpolymerization of vinyl acetate (VAc)-containing latexes with tert-butyl hydroperoxide (TBH)/ascorbic acid (AsA) as a redox initiation system was investigated. Volatile organic compounds (VOCs) such as acetone and tert-butyl alcohol were prod

The study by DSC of two bismaleimide monomers (binary system BMI/BMI) mixed in different proportions led us to propose a phase diagram. The concept of a eutectic mixture having special thermal properties has thus been demonstrated. The eutectic melti

Isothermal kinetic results were obtained for reactions between aromatic diamines with variable steric hindrance and two bismaleimide monomers, one with a structure hindered a from the two maleimide functions (BMEt) and the other not (BM). In the temp

The solid state cross-linking reactions occurring after the thermal priming of different bismaleimide monomers with variable steric hindrance were examined. As a result of the insolubility of the materials, monitoring reaction mixtures over time requ

Differential scanning calorimetry analysis of two bismaleimide monomers (N-N-diphenylmethane-4,4′-bismaleimide and m -phenylenebismaleimide) mixed in different proportions has enabled a phase diagram to be constructed. There is a relationship betwe
