Abstract
The effect of molecular structure on density has been examined in high molecular weight esters (molecular weight 300-900), having varying degrees of branching. Densities were calculated from an empirical equation, which agrees well with the experimental values (error ±1.5%), irrespective of branching. Since density is related to molecular pacing and hence to the molecular rotation, in n-alkanes, the glass transition temperature (Tg) and density both increase with molecular weight, and hence Tg is directly related to the density.
