Abstract
AbstractChlorinated polyesters were synthesized from the following acid di‐chlorides: 2,3,5,6‐tetrachloro‐1,4‐terephthaloyl (I), 2,3,5,6‐tetrachloro‐1,4‐phenylenediacetyl (II), and 2,3,5,6‐tetrachloro‐1,4‐phenylenedi(oxyacetyl) (III), and bisphenol A, under phase transfer conditions, using several ammonium and phosphonium salts as catalysts and a biphasic CH2Cl2/NaOH system. The influence of the nature of the catalysts and the reaction times were evaluated by the yields and ηinh of the polyesters. The reactivity of the monomers was I<II<III, due to the smaller influence of the tetrachlorinated ring when there is a spacer group between the aromatic ring and the acid chloride group.
