Influence of main indexes of chlorinated polyethylene (CPE) on modification of rigid PVC(2)… Effect of different volatile CPE on PVC modification:CPE manufacturers generally use aqueous phase (acid phase) suspension chlorination process, in the chlorination reaction process, some hydrogen atoms in polyethylene molecules are replaced by chlorine atoms, resulting in chlorinated polyethylene and hydrogen chloride. Since the production of CPE is carried out in suspension an…
