ABSTRACT:
Monoesters and macrocyclic diesters of 2,2,4-trimethyl-1,3-pentanediol and phthalic acid or a derivative thereof are described. Methods by which such monoesters and diesters may be prepared are also described. The mono- and diesters according to the invention are useful in the preparation of clear, hard thermoplastic polymers. The thermoplastic polymers are useful in coatings, inks, reinforced plastics and packaging materials.
