Abstract

Procedimiento continuo para la obtención de arilatos de polialquileno A) que contienen agentes lubricantes y agentes de nucleación, en el que se esterifica, o bien transesterifica un ácido dicarboxílico aromático o su éster, o bien derivados que forman ésteres, con un exceso molar de un dihidroxicompuesto alifático al menos en dos zonas de temperatura, y se policondensa el producto de transesterificado o bien esterificado obtenido, caracterizado porque al alcanzar al menos un 80 % del índice de viscosidad deseado se añaden agentes lubricantes B) y agentes de nucleación C) a la fusión polímera, y en caso dado se condensa adicionalmente la fusión, y a continuación se descarga, se enfría y se granula.
