Polypropylene grafted maleic anhydride (PP-MA, 2500 g mole(-1)) has demonstrated its unique capability to synthesize 1-D ferromagnetic hard (292.7 Oe) γ-Fe2O3 nanochains made of ~24 nm nanoparticles vs. PP-MA with 8000 g mole(-1) for the synthesis of 1-D ferromagnetic soft (70.5 Oe) γ-Fe2O3 nanochains (30 nm) made of flowerlike nanoparticles.

Short synthetic sequences commencing with the photosensitized [2 + 2]-cycloaddition reactions of maleic anhydride with either allyl alcohol or propargyl alcohol have been elaborated to provide access to 1,2,3-trisubstituted cyclobutanes with three differentiated one-carbon substituents and complementary stereochemical patterns. These intermediates were used to prepare three discrete stereo- and...

Poly(ethylene-g-maleic anhydride) (PEMA)/graphene nanoplatelets (xGn) (PEMA-xGn) composites were prepared by melt dispersion in an internal shear mixer. By adding dicumyl peroxide (DCP), cured poly(ethylene-g-maleic anhydride) C-PEMA was also produced. Different amounts of xGn were introduced into the PEMA in range of 0.5–5 wt. %. The effects of the sequence of feeding additives into the mixer ...
