WebGrafting through: In a "grafting through" copolymerization the reactivity ratio of monomers and macromonomers may be affected by micro-inhomogeneity of the reaction mixture in addition to the reaction mechanism. WebApr 8, 2024 · Grafting is a specialized type of plant propagation where part of one plant (the scion) is inserted into another (the rootstock or stock) in such a way that they unite and grow as a single plant. Budding is a type of grafting, with the scion consisting of a single bud attached to a piece of bark and sometimes a thin sliver of wood underneath.

WebThis method is a hybrid of two well-known methods, grafting-from and grafting-to approaches, in which the growing polymer side chains detach from the backbone, polymerize freely in solution, and then reattach to the backbone in a chain transfer step. Several parameters were investigated to determine optimal conditions for this process. WebMay 1, 2024 · High-MW side chains can be obtained through the “grafting-from” approach because the monomers can readily diffuse to the initiator sites as the polymers gradually grow from the active centers. One of the key features of this strategy is the high grafting density because of the significantly decreased steric hindrance among the side chains ...
