Polyamide, aromatic transparent

Semi-aromatic polyamides, polyphthalamide (PPA), polyarylamide (PAA), transparent amorphous polyamide (PA-T)... [Pg.406]

The aromatic polyamides (aramids) have been produced by the interfacial condensation of aromatic diamines, such as 1, 3-phen-ylenediamine and isophthaloyl chloride in chloroform. Amorphous transparent aramids with heat deflection temperatures of 160 C... [Pg.91]

Chitobiose, a disaccharide of glucosamine, possesses two amino functions, at C-2 and C-2. These amino groups reacted with aliphatic and aromatic diacicl chlorides to give linear polyamides (11),39 These polymers afforded transparent films, which showed high permeability, indicating probable utility as permeation-dialysis membranes (Scheme 5),... [Pg.143]

Partially aromatic, melt processable, polyamides are produced as random copolymers, which do not crystallize and are therefore transparent, but are still capable of high-temperature use because of their high Tg values. Several commercial polymers of this type that have glass-like clarity, high softening point, and oil and solvent resistance have been developed. For example, Trogamid T (Dynamit Nobel) contains repeat units of... [Pg.461]

It is possible to condense the aramide directly in an NMP solution and cast the solution. This process directly produces a transparent film from an aromatic polyamide dope without requiring the step of dissolving the aromatic polyamide in concentrated sulfuric acid. The process does not require any acid resistant equipment and is inexpensive. ... [Pg.431]

Amorphous Nylon Transparent aromatic polyamide thermoplastics. Produced by condensation of hexamethylene diamine, isophthalic and terephthalic acid. [Pg.184]

Amorphous Nylons n (l)When unsymmetrical monomers are use to synthesize polyamides (Nylons), the normal ability of the chains to crystallize can be disrupted and amorphous (often transparent) polymers are formed. (2) Transparent aromatic polyamide thermoplastics. Produced by condensation of hexamethylene diamine, isophthalic and terephthalic acid (Sepe MP (1998) Dynamic mechanical analysis. Plastics Design Library, Norwich, New York). [Pg.36]
