Decrease in apparent specific volume at room temperature $({\Phi }_{\nu }^{\prime })$ of 1% polyol on mixing with hydroxyethylstarch/trehalose systems, as calculated from densities in Table 1: difference between amorphous polyol specific volume and apparent specific volume of mixture (apparent loss of specific volume of polyol on mixing). Error bars reflect estimated standard errors evaluated from corresponding standard errors in density using propagation of errors.
