摘要
A new Nylon 11 (PA11)/polyethylene-octene (POE) blends compatibilized by maleic anhydride grafted mixture polyethyleneocten (POE-g-MAH) was prepared through melt blending method. The isothermal crystallization kinetics and melting behaviors of PA11/POE blends were investigated in detail by differential scanning calorimetry (DSC) and polarized optical microscope. The n values of PA11 blending with POE or POE-g-MAH are almost similar with pure PA11, which indicates that the effect of POE and POE-g- MAH on nucleation and growth of PA11 crystal is slight. The overall crystallization rate of PA11/POE blends are higher than ones of pure PA11 at the same crystallization temperatures, but they decrease significantly when POE-g-MAH is added into PA11/POE blends. DSC heating curves of both PA11 and its blends exhibit two melting peaks, but the two melting peak become weaker when POE-g-MAH is add into PA11/POE blend systems. And the spherulite size is reduced signifi cantly by the addition of POE-g-MAH compared with pure PA11 and PA11/POE blends.
