摘要：

A unique method has been developed to experimentally observe mutual diffusion of poly-(ethylene-co-methacrylic acid) (EMAA) and poly(vinyl methyl ether) (PVME) using conventional transmission FTIR spectroscopy. Using closed boundary conditions and assuming a composition-independent diffusion coefficient, a value of D = 6.5 x 10(-16) cm2/s was determined at 110-degrees-C.
