| One of the principal uses of Dimethyl Isophthalate is as an intermediate in the synthesis of polyesters. In order to obtain the structural strength needed in fibers and films the polyester must be of high molecular weight. The most efficient route to these high molecular weights is through transesterification of methyl ester with a glycol. A specially purified methyl ester is needed in this application. Isophthalate may be incorporated as the sole acid moiety in polyester fibers and films. However, it is often used in combination with other acid moieties to provide properties not available with the homopolymer. |
