  • Patent number: 4247427
    Abstract: Thermoplastic segmented copolyester elastomer consisting essentially of a multiplicity of recurring short chain ester units and long chain ester units joined through ester linkages, said short chain ester units amounting to 15 to 75 percent by weight of said copolyester and being derived from dicarboxylic acid such as an aromatic acid, e.g., terephthalic acid or a mixture of terephthalic acid and isophthalic acid, and an organic diol such as butanediol, and said long chain ester units amounting to 25 to 85 percent by weight of said copolyester and being derived from dicarboxylic acid such as an aromatic acid, e.g., terephthalic acid, or a mixture of terephthalic and isophthalic acids, and a long chain glycol such as polytetramethylene ether glycol, said copolyester having a melt index of less than 150 and a melting point of at least 90.degree. C., modified with 0.
