HYDROGENATION OF POLYESTER OLIGOMERS CONTAINING TEREPHTHALIC ACID RESIDUES |
摘要 |
Disclosed is a process of hydrogenating a polyester oligomer containing terephthalic acid residues wherein terephthalic acid residues are converted to residues of 1,4-cyclohexanedicarboxylic acid. Also disclosed is a process for the preparation of polyesters containing 1,4-cyclohexanedicarboxylic acid residues by first hydrogenating a polyester oligomer containing terephthalic acid residues and then reacting the resulting oligomer with one or more polyester-forming reactants to produce a higher molecular weight polyester. |
