Abstract
A polyester is provided that comprises as main monomer components thereof a dicarboxylic acid and a diol, including a p-quaterphenyl derivative of specific formula. The use of appropriate kinds of dicarboxylic acid for the polyester makes it possible to obtain a thermoplastic elastomer or an engineering platic material (i.e., liquid-crystal polymer).
