Poly meta phenylene isophthalamide
WebWe attempted to produce reverse osmosis membranes with 5-chloroformloxy-isophthaloyl chloride (CFIC) and m-phenylenediamine (MPD) with an interfacial polymerization technique on the polysulphone supporting film. The membranes produced were characterized using permeation experiments with salt water. WebThere are two types of aramid: the meta-aramids and the para-aramids. Production. The polymer poly-metaphenylene isophthalamide is used to make meta- aramids and the polymer p-phenylene terephthalamide to make para-aramids. Because the aramids decompose before they melt they are produced by wet and dry spinning methods.
