The free radical-polymerizable monomer preferably comprises methyl methacrylate (MMA), the initiator system preferably comprises N,N-diisopropanol-p-toluidine (DIIPT) and benzoyl peroxide (BPO), and the co-accelerator preferably comprises 1,4-diazabicyclo[2.2.2]octane (or triethylene diamine (TDA)).
