    • The invention relates to a process for making a modified thermoplastic polyester by reacting a thermoplastic polyester with a nitrogen-containing compound, wherein the thermoplastic polyester is first contacted in the solid state with an inert gas atmosphere containing at least one amino-compound of formula H 2 N-R-(X) n , wherein n is an integer ≥ 0, R = a linear, branched or cyclo-aliphatic or aromatic residue comprising 1-24 C-atoms and optionally containing hetero atoms, X= -NH 2 or another functional group reactive with the polyester, at a temperature T(a) between room temperature and the melting point T m of the polyester, during at least 1 s; and then heated to a temperature T(b) between T(a) and T m , during up to 10 hours; and thereafter solid state polymerised at a temperature T(c) between (T m -50) and T m , during up to 100 hours, where T (a)
    • 本发明涉及通过使热塑性聚酯与含氮化合物反应制备改性热塑性聚酯的方法,其中热塑性聚酯首先以含有至少一种式H2N氨基化合物的惰性气体气氛固态地接触 -R-(X)n,其中n是> = 0的整数,R =包含1-24个C原子并且任选地含有杂原子的直链,支链或环脂族或芳族残基,X = -NH2或另一个官能 在聚酯的室温和熔点Tm之间的温度T(a)下,至少1秒钟内与聚酯反应; 然后在10小时内加热到T(a)和Tm之间的温度T(b) 然后在T(a)
