A polymerizable monomer has the formula, <IMAGE> where R5 and R6 are similar or dissimilar and are selected from group consisting of hydrogen and methyl, k is an integer of 2-10, and the isopropenyl substituent on the aromatic ring is in the p-position or m-position. The polymerizable monomer can be used to prepare a high hardness transparent resin which in turn can be used to prepare a laminated transparent plastic material. |
