The effect of poly(ethylene‐ co ‐vinyl alcohol‐ co ‐vinyl mercaptoacetate) (EVASH) on the compatibilization of nylon‐6 (PA6)/low‐density polyethylene (LDPE) was investigated. EVASH was prepared from hydrolyzed EVA through an esterification reaction with mer‐captoacetic acid. Mechanical properties, differential scanning calorimetry, and scanning electron microscopy results are discussed. The mechanical properties were improved with the addition of EVASH. The compatibilizing agent also affects the crystallinity degree of both components of the blend, as indicated by the results obtained from DSC studies. The addition of EVASH results in a reduced dispersed‐phase particle size. © 1996 John Wiley & Sons, Inc.
