Alkenes, or olefins, are probably the most common polymer feedstock. The pi bonds of alkenes are inherently nucleophilic. The addition of an electrophile to an alkene results in cleavage of the pi bond, with the electrons drawn to the electrophile, and consequently a cation can be left on one end of the former ...
WebPolymers can promote rapid deposition of the desired molecules or NPs on solid materials through chain-induced interactions and gravitational sedimentation. There are strong electrostatic interactions between PA and cationic polymers (CPs), such as chitosan, [ 21 ] ε -poly-L-lysine [ 22 ] and polyethylenimine. [ 23 ] WebSep 12, 2024 · If you have studied some organic chemistry, then it seems obvious that cationic methods would be employed for the polymerisation of alkenes. After all, alkenes are nucleophilic, and so they should react readily with cationic initiators.
