Anotations

Scope note:

Creation of graft copolymers, a special type of branched copolymers in which long chains have occasional branches comprising repeat units different from those of the main chain. Such copolymers are created for a variety of diverse applications including enhanced tensile strength, controlled wettability, better pigment dispersion, and enhanced thermal stability.
