Dimethyl Terephthalate
AMOCO
Terephthalic Acid
FORMULA
DESCRIPTION Compared with unsaturated polyesters made with conventional acids, polyesters based on A M O C O IPA-95 offer a better combination of rigidity and impact strength, better strength retention after environmental aging, better resistance to acids and chemicals. They permit higher styrene levels. They offer a number of improvements in alkyd resin manufacture. Vinyl plasticizers show lower levels of lacquer marring and lower volatility while holding comparable low-temperature properties.
High quality intermediate extremely low in metals. A M O C O DMT is used in making polyester fibers, films and coatings. It can also serve as a high purity intermediate for other organic derivatives of terephthalic acid.
High quality intermediate extremely low in metals. TPA is useful in herbicides, surface coatings, and as a crosslinking agent.
TMA is a highly reactive, t r i f u n c t i o n a l c h e m i c a l w i t h an a c i d anhydride combination. These characteristics make it capable of unusual modification by reaction with a wide range of chemical groups in varying mole ratios. TMA esters combine the advantages of monomeric and polymeric vinyl plasticizers. Water systems can be formulated with TMA alkyds. AMOCO
