Abstract

APERFEIçOAMENTO INTRODUZIDO EM UM PROCESSO PARA A INTRODUçãO DE UM ADITIVO DENTRO DE UMA FUSãO DE POLìMEROS. Um processo inclui a introdução de um polímero base em uma extrusora, o aquecimento a uma temperatura suficiente para formar uma fusão de polímero, a introdução de um líquido tal qual água incluindo um aditivo com a mistura e subseqüente vaporização e ventilação do líquido para produzir um extrudado possuindo preferencialmente uma distribuição uniforme de partículas pequenas de aditivo.
