Why does methyl methacrylate not undergo cationic

Solution  9P

In cationic polymerization, the initiator is an electrophile (generally proton) that adds to

The alkene monomer, causing it to become as a cation .The initiator most often used in cationic polymerization is a Lewis acid such as cation.The initiator most often used in cationic

 Polymerization is a Lewis acid such as BF3 together with a proton donating  Lewis base such as water

The carbocation formed from methyl methacrylate is
