SYNTHESIS AND CRYSTALLIZATION BEHAVIOR OF (PP-MA)-G-PEO

A new graft copolymer (PP-MA)-g-PEO was synthesized by means of the chemical reaction between maleated polypropylene (PP-MA) and mono hydroxyl poly(ethylene oxide) (PEO-OH). The effect of reaction conditions on the degree of grafting of PEO-OH was studied. The crystallization behavior and crystallization properties of (PP-MA)-g-PEO were also studied. By means of differential scanning calorimetry (DSC) measurements, we found that there was a mutual effect on crystallization between the PP component and the PEO component in the (PP-MA)-g-PEO. The effect of PEO branching chain on the crystalline structure of PP was studied using wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS).
