A series of polyethylene glycol grafted vinylpyrrolidonemaleic anhydride copolymers [P(VMP)] was synthesized by radical copolymerization of vinylpyrrolidone, maleic anhydride and polyethylene glycol maleic acid monoester. Escherichia coli L-asparaginase was chemically modified with these copolymers.
## Abstract **Summary:** Covalent surface functionalization of carbon nanotubes with polypeptides is promising for possible medical applications. This work presents a graftβfrom approach to perform the polypeptide modification of multiwalled carbon nanotubes (MWNTs). The raw MWNTs are first amineβf
Blends of polypropylene (PP) and ethylene propylene rubber (EPR) were studied. The effect of the level of rubber addition and the ethylene content is described. The results show that the viscosity of the PP, rubber content, ethylene content, and grafted EPR by maleic anhydride (MA) are important fac
