High molecular weight copolyester resins having a high degree of alternating structure |
摘要 |
High molecular weight, linear aromatic polyesters having a very high degree of alternating microstructure are produced by reacting a hydroxyl-containing component with an excess of acid halide, recovering the bis adduct thus formed and thereafter polymerizing the bis adduct with additional hydroxy-containing components.
