MORFLEX 1129
(Dimethyl Isophthalate)
| C10H10O4 |
 |
 |
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.
