Abstract: PURPOSE:The titled copolymer capable of providing a molding of high modulus and good flexural and impact strengths, containing specified dicarboxylate units and ethylene terephthalate units as the principal structural units at a specified ratio. CONSTITUTION:The titled melt-moldable copolymer contains 25-75mol% (A) ethylene 1,2-bis(2-chlorophenoxy)ethylene-4,4'-dicarboxylate units and 75-25mol% (B) ethylene terephthalate units as principal stuructural components. While polyethylene phthalate has heretofore been widely used in, for example, tire cords in the form of fiber and magnetic tapes in the form of film, and the enhancement of its modulus has been demanded, this demand could not be satisfied. The imparting of a high modulus becomes possible by forming a copolymer containing units A in the above range.

Abstract: PURPOSE:To obtain a film with a high strength and a better running property for magnetic tapes or the like by heat treatment of a film comprising polyethylene alpha,beta-bis(2-chlorophenoxy)ethane 4,4'-dicarboxylate or the like on a specified condition after biaxial stretching thereof. CONSTITUTION:An unstretched film comprising polyether ester containing more than 85mol% of polyethylene alpha,beta-bis(2-chlorophenoxy)ethane 4,4'-dicarboxylate with the density of 1.42-1.46 is uniaxially stretched so as to range 0.06-0.23 in the double refraction within the surface of the film and 1.44-1.46 in the density and then, stretched at the right angle to this direction to make a biaxially stretched film. Then, the film thus obtained undergoes a heat treatment so as to range 1.45-1.49 in the density and 1.51-1.56 in the refractive index thicknesswise to obtain the intended film.

Abstract: PURPOSE:To prepare 4,4'-diphenyldicarboxylic acid of high purity efficiently, by converting crude 4,4'-diphenyldicarboxylic acid into a dialkali salt thereof, filtering the resultant dialkali salt, separating and washing the salt, and disproportionating or depositing the purified 4,4'-diphenyldicarboxylic acid with an acid. CONSTITUTION:Crude 4,4'-diphenyldicarboxylic acid is dissolved in an aqueous solution of an alkali, e.g. KOH, to form an aqueous solution of the dialkali 4, 4-diphenyldicarboxylate, which is then filtered to remove inorganic impurities. The resultant filtrate is then reacted with gaseous carbon dioxide to deposit the monoalkali 4,4-diphenyldicarboxylate, which is then separated washed and then disproportionated or deposited with an acid to isolate and recover the aimed purified 4,4'-diphenyldicarboxylic acid. EFFECT:An easy means utilizing the water solubility of the dialkali salt and the slight water solubility of the monoalkali salt.
