Poly(ethylene-alt-maleic anhydride), PEMA, and modified PEMA with pendent poly(ethylene glycol) oligomers (PEG3, PEG10, PEG20) in anhydrous acetone were grafted onto mechanically produced cellulose microfibrils, CNFs. The grafted CNFs had up to 4.7 mmol/g of carboxylic acid groups from the...
A new thermoplastic polyurethane (TPU) was prepared from polylactide-b-poly(ethylene glycol)-b-polylactide (soft segment) and 2,4-toluene diisocyanate (hard segment). Then, TPU in various proportions (i.e., 50, 70, and 90 wt%) was blended with poly(ethylene-alt-maleic anhydride) (PEMA)...

Fatty alcohol grafted poly(ethylene‐ alt ‐maleic anhydride) (PEMA‐ g ‐FA) are synthesized from esterification of poly (ethylene‐ alt ‐maleic anhydride) (PEMA) with tetradecanol and octadecanol. Obtained PEMA‐ g ‐FA's composites were prepared with different ratios of nanodiamond as phase ...
The hydrogen bonding was postulated to involve mainly the oxygen atoms of poly(ethylene-alt-maleic anhydride) (PEMA) and the tertiary hydrogens of polyacrylonitrile (PAN). The possibility of weak interactions between the nitrogen atoms of PAN and the tertiary hydrogens of PEMA was also visualized...
Several carboxylic acid polymers and poly(maleic anhydride) copolymers, such as poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly(styrene-alt-maleic anhydride) (PSMA), and poly(ethylene-alt-maleic anhydride) (PEMA) were grafted onto the bead surface. The chemical modifications were...
have shown that almost no paraffin was capsulated in the shell prepared through a one-step method, while paraffin/PUF microcapsules was successfully fabricated by a two-step method with the poly(ethylene-alt-maleic anhdride) (PEMA) as emulsifier [27]. Longer prepolymerization and polymerization ...
Poly(ethylene-alt-maleic anhydride)Poly(maleic anhydride-alt-1-octadecene)This study investigates the one-pot surface modification of PEMA gate insulators.Surface properties of the PEMA gate insulator could be easily modified by adding PMAO to the coating solution.The device performance of low-...
