1. Development of Carboxylated Nitrile Latices / Desenvolvimento de Látices Nitrílicos Carboxilados
In this dissertation an emulsion polymerization process of acrylonitrile, butadiene and carboxylic acid was studied, in pilot scale, for the production of carboxylated nitrile latex with high solids content directly from the reaction process, without the need of post-reaction steps of concentration. It was studied the effect of temperature, type and amount o

2. Preparação de microesferas poliestirenicas aminadas atraves de copolimerização entre estireno e aminoestireno para utilização em testes imunologicos
The synthesis of the functionalized PS particles containing amino-groups on their surfaces, was the subject of study in the present work. It consisted of two different steps of the research: development of a method for polymerization of styrene, resulting in homogeneous particle size distribution; application of the developed method to prepare PS particles c

3. Estabilização de latex polimericos por sorção de solventes organicos
The colloidal stability with regard to NaCI addition of homopolymer (PS-M and PS-LEV) polystyrene latexes and copolymer (P(SBMA), PS/PBMA and PBMA/PS) poly[styrene-co- butylmethacrylate)] latexes was modified by particle swelling with toluene and chloroform vapor, at 25°C. The latexes were obtained by aqueous emulsion polymerization. K2S2O4 and Na2S204 were
