Abstract: Miscibility of 30 phr loaded black-filled (N110) blends of polyethylene-vinyl acetate (EVAc, VAc content 28%) and polychloroprene (CR) are investigated through shear and dynamic deformations. Both shear (?a) and dynamic elongational (??E) viscosities are conducive to their miscibility as both show positive deviation for all blends, though dynamic out-of-phase (??E) viscosity shows negative-positive deviation. Both ?a and ??E follow the power law relationship with shear rate (??wa) and frequency (?), respectively. Both storage (E?) and loss (E?) modulii increases with frequency. The higher dissipative energy at around 11 Hz may be due to its syncronization with molecular vibrations of the polymer segments. The effect of rheological parameters like strain rate and temperature on the relative change in shear (RVS) and dynamic elongational (RVD) viscosities is reported for the variation of blend composition with 30 phr loaded black-filled compounds. The variation of both AVS and RVD follows a third order polynomial equation with carbon black loading in 50/50 EVAc/CR blend; all the polynomial constants are function of temperature and strain rate. © 1996 John Wiley & Sons, Inc.
