Amodel Poly

Liquid crystal aromatic polyamides (PARA), poly(meia-phenylene isophthalamide), Nomex , and poly(para-phenylene terephthalamide), Kevlar -49, were commercialized in 1961 and 1965, respectively. Amorphous aromatic polyamide, Trogamid , was introduced in 1969, and polyphthalamide Amodel in 1991.

STRUCTURE As described in several articles md patents/ this type of aromatic nylon resin is a polyamide consisting of varying portions of aliphatic and aromatic units. Hexamethylene diamine is the main aliphatic component, which may be augmented by various amounts of adipic acid. The main aromatic component is terephthalic acid, which may be augmented by lesser amounts of isophthalic acid. Depending on relative composition, Amodel (nylon 6,6 copolymer) resins can be regarded as co- and terpolymers consisting of repeat units of nylon 66, nylon 6T, and nylon 61 —poly (hexamethylene isophthalamide). The major potential difference of other aromatic nylons, such as Ultramid T from BASF, is the presence of the 61 component. 

Polyphthalamide (PPA) n. Poly( 1,2-benzene-dicarboxamide). A polyamide in which the residues of terephthalic or iosphthalic (or mixed) acid components are part of the mer unit of the chain. PPA is an advanced engineering polymer first commercially offered in 1991 by Amoco Chemical Co. (MS, USA) under the trade name Amodel .
