Cohesive energy densities of high polymers. Part II. Cohesive energy densitites of polyacrylates and polymethacrylates from swelling measurements

The cohesive energy densities (c.e.d.) of a number of polyacrylates and polymethacrylates have been estimated by swelling measurements in a series of alkyl esters. It is seen that the magnitudes of c.e.d. for polyacrylates are higher than those for polymethacrylates and in a homologous series, c.e.d. decreases with increase in the length of the alcoholic chain.
