	abstract = "A poly(methacrylamide-co-methylmethacrylate) (abbreviated PMAA-MMA) polymer support was studied for supporting a heteropolyacid (tungstophosphoric acid, H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB>) with its surface positively charged in the polymerization step. PMAA-MMA supports could be obtained in a porous form by eliminating template reagent molecules (benzylmalonic acid) combined with properly selected monomer (methacrylamide). The amount of amine groups in PMAA-MMA directly determined the amount of H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB> impregnated, because the amine groups induced a positive charge on the PMAA-MMA surface. Finally, H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB>/PMAA-MMA showed better acid catalytic activities than unsupported H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB> in alkylation of 1,3,5-trimethylbenzene with cyclohexene, which confirmed that PMAA-MMA supported H<SUB>3</SUB>PW<SUB>12</SUB>O<SUB>40</SUB> effectively.",
