Poly(ester-ether) compositions having increased thermal stability |
摘要 |
The present invention relates to poly(ester-ether) compositions and to a process for their preparation. In particular, the invention relates to poly(ester-ether) compositions obtained by reacting a polyester which is prepared from a dicarboxylic acid and an aliphatic diol with a dihydroxy aromatic compound in the presence of a metal catalyst. Incorporation of the dihydroxy aromatic compound into the polyester chain causes an increase in the Tg value and increases the thermal stability of the polyester. These poly(ester-ether) compositions are useful in molded articles of all types.
