摘要

A nonlinear crystalline polyester obtained by polycondensing monomers containing trivalent or higher polyvalent monomers selected from the group consisting of trihydric or higher polyhydric alcohols and tricarboxylic or higher polycarboxylic acid compounds in an amount of from 0.1 to 20 mol % of all monomers used for polycondensation.
