Abstract

La masa de moldeo de copolímeros lineales de poli(óxido de metileno) y aditivos usuales, que presenta un índice de fluidez MFI con 2.16 kg de peso de apoyo sobre la masa fundida a 190ºC igual o inferior a 0.8 g/10 min, de preferencia igual o inferior a 0.2 g/10 min, posee una tenacidad extraordinaria, que hace superflua la adición de modificadores del tipo elastómero. En su obtención se utiliza como iniciadores ácidos de Lewis o ácidos protonados.
