Abstract:Chemical kinetics was investigated to understand effect of shear on chemical reaction at styrene-maleic anhydride copolymer(SMA)/nylon 6(PA6) interface with fixed area through the rheological method.The main reason why sharing can improve the rate of the chemical reaction at the reactive interface was analyzed from the kinetics of the chemical reaction.The experimental results show that the rate of the chemical reaction is increased with increasing angular frequency and the strain applied at the interface,and the chemical kinetics changes from the first-order diffusion-controlled reaction to the second-order chemical reaction-controlled reaction,indicating that shear can accelerate diffusion rate of the reactive group to the interface.
Keywords:SMA  PA6  shear  interface  chemical kinetics
