摘要: Abstract Recently, Mead (J. Rheology, 38 (1994) 1797–1827) has shown, for the double reptation model with a monodisperse relaxation function, characterized by single time constant, how moments molecular weight distribution (MWD) can be determined directly from measurements of linear viscoelastic modulus. The purpose this paper is to show that result special case more general which allows inner-product functionals defined on MWD, such as its moments, measurements. applicability strategy verified and validated using synthetic data.
