Abstract
A thermoplastic ordered copolyesteramide elastomer has segments contg. (A) a diol with molecular wt. 250, (B) polyhydroxyalkylene glycols of mean molecular wt. 400-3500. These segments are linked to one another by ester bonds through a radical derived from a diesterdiamide contg. preformed amide bonds of formula R1OC.CO.R2.CO.NHR3NH. CO.R. CO.OR1 (where R1 is 1-8 C alkyl and/or 6-10C aryl and/or 4-10C cycloalkyl, and R2 and R3 are 2-30C bivalent hydrocarbon radicals). (A) is pref. 1,6-hexanediol, or its mixt. with neopentyl-glycol, and (B) is pref. tetramethyleneoxyglycol with molecular wt. 600-2000. The rigid segment of the elastomer pref. constitutes 2-80% of the polymer. Such elastomers possess good resistance to solvents, fuels and oils. They can be used at temps. >135 degrees C, sometimes near 200 degrees C. Their elastic properties are good and constant up to 120 degrees C. The use of diesterdiamides in these elastomers gives highly crystalline rigid phases with a high m.pt. and high rate of crystallisation. The m.pt. is insensitive to variations in compsn.
