Abstract

Przedmiotem wynalazku jest sposób wytwarzania granulatu polilaktydowego polegający na wytłoczeniu polilaktydu z reaktywnym związkiem wydłużającym łańcuchy w postaci terpolimeru p-alkilostyrenu, estru (met)akrylanowego i epoksydowanego (met)akrylanu o wzorze 1, przy czasie przebywania wytłaczanych składników w strefach grzewczych wytłaczarki nie przekracza 200 sekund, natomiast temperatura poszczególnych stref grzewczych i głowicy mieści się w zakresie do 200°C.
