One common type of cation exchange resin is prepared by polymerization of a mixture containing styrene and 1,4-divinylbenzene . The polymer is then treated with concentrated sulfuric acid to sulfonate a majority of the aromatic rings in the polymer.
Q.) Show the product of sulfonation of each benzene ring.
When certain cycloalkenes are used in metathesis reactions, ringopening metathesis polymerization (ROMP) occurs to form a highmolecular- weight polymer, as shown with cyclopentene as the starting material. The reaction is driven to completion by relief of strain in the cycloalkene.What products are formed by ring-opening metathesis polymerization of each alkene?
List the following group of monomers in order of decreasing ability to undergo cationic polymerization.
