摘要: The preparation of aromatic polyesters based on diphenols and iso- and terephthalic acid is carried out by solventfree transesterification of esters of the diphenols with the aromatic dicarboxylic acids, the esters of the diphenols being initially reacted with teriphthalic acid alone and subsequently reacted with isophthalic acid after at least 80% of the terephthalic acid has undergone reaction.
