Abstract
Procedimiento para la obtención de masas de moldeo termoplásticas, resistentes al impacto, caracterizado porque comprende, en una primera etapa, polimerizar una mezcla de 30 a 85 partes en peso de un monómero vinílico aromático, con 1 a 20 partes en peso partes en peso de un ácido mono o dicarboxílico alfa, beta - insaturado o de su anhídrido y con 14,9 a 50 partes en peso de un ester de un ácido mono o dicarboxílico en presencia de un prolongador de cadenas, con auxilio de un iniciador radicalar, efectuándose la polimerización de moco continuo en un reactor de tanque con agitación ideal, durante un tiempo de residencia comprendido entre 10 y 240 minutos y una tempera tura comprendida entre 60 y 150ºC, hasta un grado de polimerización de 20 a 50% en moles y, en una segunda etapa, se libera en continuo la mezcla de copolímero, que contiene monomeros residuales, por vacío o por boroteo de un gas inerte de dichos monomeros residuales hasta un contenido inferior al 1% en peso, y finalmente, semezclan de 1 a 20 partes en peso de polímero así obtenido (1) con 1,60 a 93 partes en peso de una poliamida (2) y 2,6 a 30 partes en peso de un polietileno (3) en una extrusora a una temperatura comprendida entre 200 y 320ºC.
