Process for preparing ether-ester-amide block polymers. It consists in the reaction, in the molten state of a dicarboxylic polyamide having COOH end groups with a polyoxyalkylene glycol having hydroxyl end groups in the presence of metallic tetraalkoxide(s) as catalysts. The tetraalkoxid
Thermoplastic polymer cover for golf balls.The thermoplastic polymer material constituting the cover consists of a poly(ether-ester-amide) sequenced copolycondensate having special characteristics.Such a cover has good mechanical characteristics and confers on the golf balls so covered a
A process to synthesize poly (ether-ester-amide) sequence copolycondensates by the reaction in a molten condition between a dicarboxylic polyamide, in which the carboxylic functions are located at the chain-ends, and a polyoxyalkoylene with hydroxylated chain-ends, in the presence of a
