Influence of molecular masses (MM av), molecular-mass distribution (MMD) and heterogeneity on kinetics of residual strains is considered in case of solidification of industrial brands epoxy oligomers (EO) of industrial brands. Data on influence of MM av, MMD and phase heterogeneity on kinetics of residual strains are for the first time obtained. Correlation of shrinkage kinetics and residual strains is established at EO solidification.
