is the principal aromatic dibasic acid used in coatings, and adipic acid is the principal aliphatic diacid.
In a manner similar to that of the polycarbonate oligomer, an hydroxy end-capped oligomer of bishydroquinone and isophthalic acid
(referred to as HQ/IPA/HQ) was prepared, having the following formula:
The presence of isophthalic acid
and neopentyl glycol units in the polymer, inhibit close packing, increase flexibility, and create cavities into which diffusion of the dye can occur.
After adding the isophthalic acid
, the temperature is raised to 230[degrees]C to form the silicone-alkyd copolymeer.
Polyester polyols containing isophthalic acid
(PIA) weather extremely well, but they have poor flexibility.
Eastman Chemical's purified terephthalic acid and isophthalic acid
plants previously announced for North America will be built in Kingsport, at Tennessee Eastman Division.
An isopolyester resin, based on Amoco's isophthalic acid
, is used to manufacture the grating system.

Amorphous poly(ethylene terephthalate) (aPET) is a linear aromatic copolymer synthesized by using the isophthalic acid
and terephthalaic acid and ethylene glycol monomers.
Abstract A series of polyester polyol resin was synthesized by using 1,4-cyclohexanedimenthanol (1,4-CHDM) and three different diacids: 1,3-cyclohexanedicarboxylic acid (1,3-CHDA), isophthalic acid
(IPA) and adipic acid (AA).
Hambana Petrochemical Ltd will have to import raw materials of 453,000Mt of Purified Terephthalic Acid, 183,600 Mt of Mono-Ethylene Glycol and 10,800 Mt of Purified Isophthalic Acid
