Modified polyesters and processes for manufacturing the same |
摘要 |
<p>Disclosed herein are processes for manufacturing modified polyesters. An esterification reaction of diacid, diol and a branching agent having at least three carboxyl groups is carried out at a temperature of about 180 to 300°C and a pressure of about 1 to 4 bar to obtain a product of esterification. A polycondensation reaction of the product of esterification and a diamine is carried out at a pressure below about 0.01 bars to obtain the modified polyester.</p> |
