Versuchsvorschrift

The terephthalate or isophthalate from Stage I is in the form of a neopentyl glycol or cyclohexane dimethanol terephthalic acid oligomer which is then reacted in in Stage II with trimellitic anhydride or acid to provide a neopentyl or cyclohexane-terephthalate or isophthalate-trimellitate. The mole ratio of the neopentyl or cyclohexane terephthalate or isophthlate to the trimellitic anhydride or acid is in the range of between about 2.5 and about 5.5.
