Arranged Polymers are widely used in almost 50 years. These polymers are used in the textile and air industries. A Liquid Crystals Polymer is arranged polymer with special property[1]. Behavior of liquid Crystal was reported first time by Austrian Botanist and Friedrich Reinitzer. Kwolek (1965)explained about the anisotropic solutions of aromatic polyamide in alkyl amide solvents. The progress of this research led to creating poly para phenylene terephthalamide.The polymer solution in concentrated sulfuric acid is as a short-range order [2]. In this paper PPTA and nylon6 mixtures particles size distribution were studied.
