摘要：

A new group contribution method, GCVOL, for the prediction of liquid densities as a function of the temperature is proposed. A table for 36 different group volume parameters is given. Using the proposed method liquid densities for even strongly polar solvents can be predicted with an error of approximately 1% in the temperature range between the melting temperature and the normal boiling point. Densities of amorphous polymers are predicted with an average error of 2.7%. The proposed method is able to describe densities for the complete molecular range, covering solvents, oligomers, and polymers.
