Modification by grafting

The Cassia angustifolia GaM possesses the potential to become a new source of commercial gum due to its high content in the endosperm (about 50%) and its valuable rheological properties. It was suggested, in a similar way as for other GaMs, for usage as an additive in pharmaceutical formulations [188, 246]. Also the Ipomoea seed gum in its natural form, and after modification by grafting, has the potential to be used as a commercial gum [178].

From this standpoint, cellulose modification by grafting is exceptionally promising. Recently, grafting has become a popular method of modifying various high molecular weight compounds1,2. ... 

Chemical modification of polymers affords an opportunity to modify undesired properties that would limit or even invalidate the potential usefulness of these materials. Polypropylene polymers are a good example, because their applications depend on their stereoregularity. Atactic homopolymer, a by-product from industrial polymerization reactors, lacks good material properties. However, its chemical modification by grafting with polar groups, one can convert it into a useful new material, as suggested by Natta (37).

Polymeric Membranes Surface Modification by Grafting to Method and Fabrication of Multilayered Assemblies... 

The ultimate purpose of surface modification by graft polymerization, as diseussed previously, is to alter surface properties of the substrate so as to manipulate its physicochemical interactions with the surrounding fluid medium. Knowledge of surface properties such as molecular weight, surface density, and chemical stmcture is essential to predicting solute-substrate and solvent-substrate interactions, which in turn govern the macroscopic behavior (adsorption, wetting) of the modified surface. 

Nevertheless, mechanical stability of electrospun PVDF-based fibrous membranes is inherently weak to withstand the strong tension during battery assembly process, which severely restricts their practical applications. Chemical modification by grafting or crosslinking with functional reagents has been proved as an effective approach to improve the mechanical property of PVDF [25]. Kader et al. reported the preparation of electrospun poly(vinylidene fluoride)-graft-poly(tert-butyl...
