The effect of polymer additives on the growth of vapour bubbles in an infinite volume of superheated fluid was analysed in part 1 of the present paper. The second part discusses the reasons for the experimentally observed qualitatively different (with respect to a pure solvent) changes in the heat transfer coefficient in bubble boiling of polymer solutions with different macromolecule content. An explanation is suggested for the phenomenon of heat transfer enhancement in boiling of diluted solutions of high polymers with a concentration of about 0.01%.
