    Abstract: A thermoplastic resin composition comprises units represented by the amide formula (I) and the ester formula (II) wherein said amide units are present as a physical mixture in said resin or as a polymer with the repeating ester units to impart an enhanced crystallization rate as compared to said resin without said amide units of formula (I), said amide units being present in an effective amount to decrease the difference between the temperature of melting and the temperature of crystallization of said resin to an amount less than 5 mole percent of amide units of formula (I) based on the moles of ester units of formula (II).

    Abstract: PROBLEM TO BE SOLVED: To simpler and more economically obtain ester amides and polyesteramides through a fewer processes without requiring the complicated purification of an intermediate by the transesterification of a dialkyl terephthalate. SOLUTION: This method is to conduct the transesterification of (A) a dialkyl terephthalate into (B) an alkyl aryl terephthalate so as to making the component B exist in the reaction product, to catalytically react the reaction product with an alkylene diamine so as to form a bis-ester amide by reacting at least a portion of the component B with the above alkyl alkylene or arylene diamine and to polymerize the bis-ester amide with a diol to form a polyesteramide. The transesterification is preferably carried out by reacting the component A with a suitable phenoxy derivative such as a diphenyl terephthalate.

    Abstract: PROBLEM TO BE SOLVED: To recover bis-phenol A from compositions containing reaction residue of a dihydric phenol, particularly bis-phenol A units. SOLUTION: A bis-phenol A-containing polymer is roughly crushed and the crushed granules are treated with an organic swelling solvent which is compatible to water such as an alcohol or other solvent and can be readily distilled off from the aqueous solution for a time enough to swell the crushed granules. Then, the swollen crushed granules are brought into contact with an aqueous ammonia which can selectively cleave the ester bonds of the bis-phenol A residual units at a temperature of >=25 deg.C to form the liquid phase and the solid phase. The liquid phase is separated from the solid phase, ammonia and the organic swelling solvent are distilled out of the liquid phase to obtain an aqueous solution containing dissolved urea, partially precipitated bis-phenol A. A sufficient amount of water is added to the solution to precipitate bis-phenol A to form the liquid phase the solid phase. Finally, the bis phenol A of the solid phase is recovered and dried.
