FILM FORMATION OF POLY (p-PHENYLENE TEREPHTHALAMIDE) FROM SULPHURIC ACID SOLUTION

A novel process for the formation of poly (p-phenylene terephthalamide) (PPTA) film from liquid crystalline sulphuric acid solution was developed. A homogeneous and transparent PPTA film is very difficult to obtain from sulphuric acid solution owing to the highly anisotropic flow properties of the s...
