Abstract

MÉTODO PARA FAZER UM POLÍMERO SOLÚVEL EM ÁGUA, UM POLÍMERO SOLÚVEL EM ÁGUA ASSIM PRODUZIDO E UMA COMPOSIÇÃO DE POLÍMERO SOLÚVEL EM ÁGUA PROCESSÁVEL POR FUNDIÇÃO. Um método para criar um polímero solúvel em água processável, o método compreendendo as etapas de: extrusão de uma composição de polímero solúvel em água de um barril de extrusora sem o uso de uma matriz, em que o barril de extrusora não é ventilado além de sua saída de extrusora, para produzir um extrudado de polímero de forma irregular; direcionar o extrudado de polímero de formato irregular para um transportador resfriado para resfriar o extrudado de polímero de formato irregular abaixo de 60°C; e granular o extrudido de polímero de forma irregular para formar um granulado.
