Abstract
Empleo de masas de moldeo de poliéster termoplásticas, que contienen A)de un 80 hasta un 100 % en peso de un arilato de polialquileno con una semianchura de las exotermas de cristalización de 5ºC, y B)de un 0 hasta un 20 % en peso de otros aditivos, ascendiendo los porcentajes en peso de los componentes A) y B) a un 100 %, para la obtención de cuerpos moldeados mediante moldeo por soplado, extrusión de perfiles y/o extrusión de tubos, caracterizado porque a)se esterifican o bien transesterifican en una primera etapa un ácido dicarboxílico aromático o sus ésteres o bien sus derivados formadores de ésteres con un exceso molar de un compuesto dihidroxílico, b)se precondensa en una segunda etapa el producto de transesterificación o bien de esterificación obtenido según a), y c)se policondensa en una tercera etapa el producto obtenible de b) hasta un VZ de al menos 158 ml/g, llevándose a cabo la etapa a) y b) del procedimiento en al menos dos zonas detemperatura, agregando antes o después de la policondensación c), antes del enfriamiento de la fusión, en caso dado, el componente B) y haciendo reaccionar el compuesto dihidroxílico antes de la etapa a) primero con un catalizador y seguidamente con un compuesto alcalino(térreo).
