Abstract

<B>PROCESSO PARA FORMAçãO DE PELìCULAS, FIBRAS E TIRAS CONTìNUAS DE BASE A PARTIR DE POLìMEROS DE TERMOCURA<D> é revelado um processo para formação de fibras, películas e tiras contínuas fibrosas a partir de polímeros de termocura. O processo inclui primeira formação de composição de prepolímero ativável por energia. A composição de prepolímero é extrusada através de uma matriz, a fim de formar artigos poliméricos. Uma vez extrusada através da matriz, a composição de prepolímero é então contatada com uma fonte de energia que faz com que a composição de prepolímero sofra, irreversivelmente, uma transformação química para formar um polímero de termocura. Os artigos polímeros curados podem então ser coletados na superfície e usados conforme desejado. A fonte de energia usada para ativar a composição prepolímero pode ser, por exemplo, uma corrente de gás aquecido, ondas sonoras ultra sónicas ou uma fonte de radiação.
