Abstract

PROCESSO PARA A PREPARAÇÃO DE PARTÍCULAS DE POLIÉSTER COM ALTA CARGA EM UMA LINHA. A invenção refere-se a um processo, assim como a um equipamento, para a preparação de um poliéster termoplástico com as seguintes etapas: a) preparação de partículas de prepolímero de poliéster, b)cristalização das partículas de prepolímero de poliéster para preparação de partículas de prepolímero de poliéster semicristalinas, c) aquecimento das partículas de prepolímero de poliéster semicristalinas até uma temperatura de reação apropriada para preparação de partículas de prepolímero de poliéster aquecidas, d) reação das partículas de prepolímero de poliéster aquecidas para preparação de partículas de polímero de poliéster com uma viscosidade intrínseca entre 0,70 e 0,95 dl/g. A reação na etapa d) ocorre em pelo menos um reator, através do qual as partículas escoam por gravidade. O tempo de residência no reator se situa entre 6 e 30 horas. As partículas são alimentadas pelo menos na etapa (d) com uma vazão mássica entre 40 e 100 toneladas por hora. A presente invenção se destaca pelo fato de que a velocidade de assentamento das partículas no reator se situa entre 2 e 6 metros por segundos.
