Abstract: A liquid crystal resin comprises structural units derived from at least two types of aromatic diols. The liquid crystal resin generates 100 ppm or less of acetic acid gas, less than 20 ppm of phenol gas, and less than 100 ppm of carbon dioxide gas when the liquid crystal resin is retained at a melting point +10°C (or at 335°C when the melting point is less than 325°C) for 30 minutes in a helium gas atmosphere. The present invention provides a liquid crystal resin or a composition containing this resin by which metal corrosion, clouding of glass, bulging of molded articles, and the like are reduced.

This resin composition for a foamed molding is foamed and molded so that a foamed molding with an expansion ratio of 2-20 is obtained. In the formulas, R1 is at least one kind of group selected from among groups represented by formulas V, VI, etc.; R2 is at least one kind of group selected from among groups represented by formulas VII, VIII, etc.; and X is H or Cl. Preferably, the sum of structural units represented by formulas I and If accounts for 80-95 mol% of the sum of structural units represented by formulas I to III, and the structural unit represented by formula III accounts for 20-5 mol% of the sum of structural units represented by formulas I to III.
